+ * DOC: B+Tree basics
+ *
+ * A B+Tree is a data structure for looking up arbitrary (currently allowing
+ * unsigned long, u32, u64 and 2 * u64) keys into pointers. The data structure
+ * is described at http://en.wikipedia.org/wiki/B-tree, we currently do not
+ * use binary search to find the key on lookups.
+ *
+ * Each B+Tree consists of a head, that contains bookkeeping information and
+ * a variable number (starting with zero) nodes. Each node contains the keys
+ * and pointers to sub-nodes, or, for leaf nodes, the keys and values for the
+ * tree entries.
+ *
+ * Each node in this implementation has the following layout:
+ * [key1, key2, ..., keyN] [val1, val2, ..., valN]
+ *
+ * Each key here is an array of unsigned longs, geo->no_longs in total. The
+ * number of keys and values (N) is geo->no_pairs.

+ * struct sx150x_platform_data - config data for SX150x driver
+ * @gpio_base: The index number of the first GPIO assigned to this
+ * GPIO expander. The expander will create a block of
+ * consecutively numbered gpios beginning at the given base,
+ * with the size of the block depending on the model of the
+ * expander chip.
+ * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
+ * instead of as an oscillator, increasing the size of the
+ * GP(I)O pool created by this expander by one. The
+ * output-only GPO pin will be added at the end of the block.
+ * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
+ * for each IO line in the expander. Setting the bit at
+ * position n will enable the pull-up for the IO at
+ * the corresponding offset. For chips with fewer than
+ * 16 IO pins, high-end bits are ignored.
+ * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
+ * resistor for each IO line in the expander. Setting the
+ * bit at position n will enable the pull-down for the IO at
+ * the corresponding offset. For chips with fewer than
+ * 16 IO pins, high-end bits are ignored.
+ * @io_open_drain_ena: A bit-mask which enables-or disables open-drain
+ * operation for each IO line in the expander. Setting the
+ * bit at position n enables open-drain operation for
+ * the IO at the corresponding offset. Clearing the bit
+ * enables regular push-pull operation for that IO.
+ * For chips with fewer than 16 IO pins, high-end bits
+ * are ignored.
+ * @io_polarity: A bit-mask which enables polarity inversion for each IO line
+ * in the expander. Setting the bit at position n inverts
+ * the polarity of that IO line, while clearing it results
+ * in normal polarity. For chips with fewer than 16 IO pins,
+ * high-end bits are ignored.
+ * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
+ * is connected, via which it reports interrupt events
+ * across all GPIO lines. This must be a real,
+ * pre-existing IRQ line.
+ * Setting this value < 0 disables the irq_chip functionality
+ * of the driver.
+ * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
+ * IRQ lines will appear. Similarly to gpio_base, the expander
+ * will create a block of irqs beginning at this number.
+ * This value is ignored if irq_summary is < 0.
+ * @reset_during_probe: If set to true, the driver will trigger a full
+ * reset of the chip at the beginning of the probe
+ * in order to place it in a known state.

+ * Locking
+ * =======
+ *
+ * @lock is a softirq-safe spinlock protecting @queue as well as
+ * @cur_slot, @mrq and @state. These must always be updated
+ * at the same time while holding @lock.
+ *
+ * The @mrq field of struct dw_mci_slot is also protected by @lock,
+ * and must always be written at the same time as the slot is added to
+ * @queue.
+ *
+ * @pending_events and @completed_events are accessed using atomic bit
+ * operations, so they don't need any locking.
+ *
+ * None of the fields touched by the interrupt handler need any
+ * locking. However, ordering is important: Before EVENT_DATA_ERROR or
+ * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
+ * interrupts must be disabled and @data_status updated with a
+ * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
+ * CMDRDY interupt must be disabled and @cmd_status updated with a
+ * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
+ * bytes_xfered field of @data must be written. This is ensured by
+ * using barriers.

/**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ * these registrations are ignored until the interface type is
+ * changed again. This means that changing the interface type can
+ * lead to a situation that couldn't otherwise be produced, but
+ * any such registrations will be dormant in the sense that they
+ * will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ * be lost, thus blocking readers forever.
+ * If this synchronization point is not a mutex, but a spinlock or
+ * spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ * are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ * pure reads. But if they have to fetch many values, it's better to not allow
+ * preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ * (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ * read partial values)
+ *
+ * 7) For softirq uses, readers can use u64_stats_fetch_begin_bh() and
+ * u64_stats_fetch_retry_bh() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])
+ *
+ * spin_lock_bh(...) or other synchronization to get exclusive access
+ * ...

+ * stats->bytes64 += len; // non atomic operation
+ * stats->packets64++; // non atomic operation

- *
- * The vstusb module is a standard usb 'client' driver running on top of the
- * standard usb host controller stack.
- *
- * In general, vstusb supports standard bulk usb pipes. It supports multiple
- * devices and multiple pipes per device.
- *
- * The vstusb driver supports two interfaces:
- * 1 - ioctl SEND_PIPE/RECV_PIPE - a general bulk write/read msg
- * interface to any pipe with timeout support;
- * 2 - standard read/write with ioctl config - offers standard read/write
- * interface with ioctl configured pipes and timeouts.
- *
- * Both interfaces can be signal from other process and will abort its i/o
- * operation.
- *
- * A timeout of 0 means NO timeout. The user can still terminate the read via
- * signal.
- *
- * If using multiple threads with this driver, the user should ensure that
- * any reads, writes, or ioctls are complete before closing the device.
- * Changing read/write timeouts or pipes takes effect on next read/write.
- *

+ * check types return XZ_OPTIONS_ERROR if
+ * XZ_DEC_ANY_CHECK was not defined at build time.
+ * @XZ_MEM_ERROR: Allocating memory failed. This return code is

+ * with XZ_DYNALLOC. The amount of memory that was
+ * tried to be allocated was no more than the
+ * dict_max argument given to xz_dec_init().

+ * @XZ_OPTIONS_ERROR: This implementation doesn't support the requested
+ * compression options. In the decoder this means
+ * that the header CRC32 matches, but the header
+ * itself specifies something that we don't support.
+ * @XZ_DATA_ERROR: Compressed data is corrupt.

+ * to XZ code cannot consume any input and cannot produce any new output.
+ * This happens when there is no new input available, or the output buffer
+ * is full while at least one output byte is still pending. Assuming your
+ * code is not buggy, you can get this error only when decoding a compressed
+ * stream that is truncated or otherwise corrupt.
+ *
+ * In single-call mode, XZ_BUF_ERROR is returned only when the output buffer
+ * is too small or the compressed input is corrupt in a way that makes the
+ * decoder produce more output than the caller expected. When it is

+ * limiting the maximum memory usage to a sane value to prevent running the
+ * system out of memory when decompressing streams from untrusted sources.
