2010-10-30fs/compat.c: fix build on MIPS/s390wu zhangjin
The definition of PAGE_CACHE_MASK in <linux/pagemap.h> is needed to use MAX_RW_COUNT, and on x86-64 that gets done indirectly through the architecture header includes. But on MIPS and s390 that doesn't happen, and we need to make sure that fs/compat.c includes pagemap.h explicitly. Introduced in commit 435f49a518c7 ("readv/writev: do the same MAX_RW_COUNT truncation that read/write does").

2010-10-30audit mmapAl Viro
Normal syscall audit doesn't catch 5th argument of syscall. It also doesn't catch the contents of userland structures pointed to be syscall argument, so for both old and new mmap(2) ABI it doesn't record the descriptor we are mapping. For old one it also misses flags. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-10-30audit: Call tty_audit_push_task() outside preempt disabledThomas Gleixner
While auditing all tasklist_lock read_lock sites I stumbled over the following call chain: audit_prepare_user_tty() read_lock(&tasklist_lock); tty_audit_push_task(); mutex_lock(&buf->mutex); --> buf->mutex is locked with preemption disabled. Solve this by acquiring a reference to the task struct under rcu_read_lock and call tty_audit_push_task outside of the preempt disabled region. Move all code which needs to be protected by sighand lock into tty_audit_push_task() and use lock/unlock_sighand as we do not hold tasklist_lock.

2010-10-30mtd: Remove redundant mutex from mtd_blkdevs.cDavid Woodhouse
In commit 2a48fc0ab24241755dc93bfd4f01d68efab47f5a ('block: autoconvert trivial BKL users to private mutex'), Arnd replaced the BKL usage with a mutex. However, Maxim has already provided a better fix in commit 480792b7bf188c29b8d4b10fee65c3a06ec5dbf7 ('mtd: blktrans: kill BKL'), which was simply to remove the BKL without replacing it — since he'd already made it do all necessary locking for itself.

Recent changes in s3c gpio break mini2440 board and may be others. The problem is that mach-mini2440.c: mini2440_init() (where we call s3c_gpio_setpull()) is called before s3c2440.c: s3c2440_init() (where we initialize s3c24xx_gpiocfg_default.set_pull function pointer).

2010-10-29msm: fix compile failure when no debug uart is selectedDaniel Walker
If the board has a debug uart the user is given a choice of which uart to use. The user can also select NONE, which means not to use one. In most of our header files when NONE is selected nothing is defined for MSM_DEBUG_UART_PHYS or MSM_DEBUG_UART_BASE. This causes a compile failure in debug-macro.S which expect something to be defined there. Example of the failure, arch/arm/kernel/built-in.o: In function `hexbuf': linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_PHYS' linux-2.6/arch/arm/kernel/debug.S:186: undefined reference to `MSM_DEBUG_UART_BASE' This fixes the compile failure by adding an ifdef to debug-macro.S that removes all the debug uart code in the case of NONE. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>

2010-10-29Btrfs: add START_SYNC, WAIT_SYNC ioctlsSage Weil
START_SYNC will start a sync/commit, but not wait for it to complete. Any modification started after the ioctl returns is guaranteed not to be included in the commit. If a non-NULL pointer is passed, the transaction id will be returned to userspace. WAIT_SYNC will wait for any in-progress commit to complete. If a transaction id is specified, the ioctl will block and then return (success) when the specified transaction has committed. If it has already committed when we call the ioctl, it returns immediately. If the specified transaction doesn't exist, it returns EINVAL. If no transaction id is specified, WAIT_SYNC will wait for the currently committing transaction to finish it's commit to disk. If there is no currently committing transaction, it returns success. These ioctls are useful for applications which want to impose an ordering on when fs modifications reach disk, but do not want to wait for the full (slow) commit process to do so. Picky callers can take the transid returned by START_SYNC and feed it to WAIT_SYNC, and be certain to wait only as long as necessary for the transaction _they_ started to reach disk. Sloppy callers can START_SYNC and WAIT_SYNC without a transid, and provided they didn't wait too long between the calls, they will get the same result. However, if a second commit starts before they call WAIT_SYNC, they may end up waiting longer for it to commit as well. Even so, a START_SYNC+WAIT_SYNC still guarantees that any operation completed before the START_SYNC reaches disk.

2010-10-29Btrfs: async transaction commitSage Weil
Add support for an async transaction commit that is ordered such that any subsequent operations will join the following transaction, but does not wait until the current commit is fully on disk. This avoids much of the latency associated with the btrfs_commit_transaction for callers concerned with serialization and not safety. The wait_for_unblock flag controls whether we wait for the 'middle' portion of commit_transaction to complete, which is necessary if the caller expects some of the modifications contained in the commit to be available (this is the case for subvol/snapshot creation).

2010-10-29Btrfs: fix deadlock in btrfs_commit_transactionSage Weil
We calculate timeout (either 1 or MAX_SCHEDULE_TIMEOUT) based on whether num_writers > 1 or should_grow at the top of the loop. Then, much much later, we wait for that timeout if either num_writers or should_grow is true. However, it's possible for a racing process (calling btrfs_end_transaction()) to decrement num_writers such that we wait forever instead of for 1. Fix this by deciding how long to wait when we wait. Include a smp_mb() before checking if the waitqueue is active to ensure the num_writers is visible. Signed-off-by: Sage Weil <sage@newdream.net> Signed-off-by: Chris Mason <chris.mason@oracle.com>
