[PATCH] lockdep: irqtrace subsystem, core

2006-07-03T22:27:03+00:00

Accurate hard-IRQ-flags and softirq-flags state tracing.

This allows us to attach extra functionality to IRQ flags on/off
events (such as trace-on/off).

[PATCH] lockdep: add local_irq_enable_in_hardirq() API

2006-07-03T22:27:00+00:00

Introduce local_irq_enable_in_hardirq() API.  It is currently aliased to
local_irq_enable(), hence has no functional effects.

This API will be used by lockdep, but even without lockdep this will better
document places in the kernel where a hardirq context enables hardirqs.

[PATCH] lockdep: add disable/enable_irq_lockdep() API

2006-07-03T22:27:00+00:00

lockdep wants to use the disable_irq()/enable_irq() prototypes before they are
provied by the platform's asm/irq.h.  So move them out of the
CONFIG_GENERIC_HARDIRQS define - all architectures have a common prototype for
this anyway.

Add special lockdep variants of irq line disabling/enabling.

These should be used for locking constructs that know that a particular irq
context which is disabled, and which is the only irq-context user of a lock,
that it's safe to take the lock in the irq-disabled section without disabling
hardirqs.

[PATCH] genirq:fixup missing SA_PERCPU replacement

2006-07-03T00:29:22+00:00

The irqflags consolidation converted SA_PERCPU_IRQ to IRQF_PERCPU but
did not define the new constant.

[PATCH] irq-flags: consolidate flags for request_irq

2006-07-02T20:58:46+00:00

The recent interrupt rework introduced bit value conflicts with sparc.
Instead of introducing new architecture flags mess, move the interrupt SA_
flags out of the signal namespace and replace them by interrupt related flags.

This allows to remove the obsolete SA_INTERRUPT flag and clean up the bit
field values.

This patch:

Move the interrupt related SA_ flags out of linux/signal.h and rename them to
IRQF_ .  This moves the interrupt related flags out of the signal namespace
and allows to remove the architecture dependencies.

SA_INTERRUPT is not needed by userspace and glibc so it can be removed safely.

The existing SA_ constants are kept for easy transition and will be
removed after a 6 month grace period.

[PATCH] adjust handle_IRR_event() return type

2006-06-23T14:43:08+00:00

Correct the return type of handle_IRQ_event() (inconsistency noticed during
Xen development), and remove redundant declarations.  The return type
adjustment required breaking out the definition of irqreturn_t into a
separate header, in order to satisfy current include order dependencies.

[BLOCK] ll_rw_blk: Enable out-of-order request completions through softirq

2006-01-09T15:02:34+00:00

Request completion can be a quite heavy process, since it needs to
iterate through the entire request and complete the bio's it holds.
This patch adds blk_complete_request() which moves this processing
into a dedicated block softirq.
