mutex: improve header comment to be actually informative about the API

2008-10-30T18:55:00+00:00

Impact: improve documentation

It's nice to say that mutex_trylock follows the spin_trylock convention.
It's a lot nicer if the comment also says which that is...  make it so.

Add mutex_lock_killable

2007-12-06T22:37:59+00:00

Similar to mutex_lock_interruptible, it can be interrupted by a fatal
signal only.

lockdep: fixup mutex annotations

2007-10-11T20:11:12+00:00

The fancy mutex_lock fastpath has too many indirections to track the caller
hence all contentions are perceived to come from mutex_lock().

Avoid this by explicitly not using the fastpath code (it was disabled already
anyway).

mutex_lock_interruptible(): add __must_check

2007-05-09T19:30:49+00:00

It's not sane to use mutex_lock_interruptible() and to then ignore the result.

Ditto down_interruptible(), but I'm lazy.

[PATCH] fix various kernel-doc in header files

2007-01-26T21:51:00+00:00

Fix a number of kernel-doc entries for header files in include/linux by
making sure they begin with the appropriate '/**' notation and use @var
notation.

[PATCH] lockdep: avoid lockdep warning in md

2006-12-08T16:28:39+00:00

md_open takes ->reconfig_mutex which causes lockdep to complain.  This
(normally) doesn't have deadlock potential as the possible conflict is with a
reconfig_mutex in a different device.

I say "normally" because if a loop were created in the array->member hierarchy
a deadlock could happen.  However that causes bigger problems than a deadlock
and should be fixed independently.

So we flag the lock in md_open as a nested lock.  This requires defining
mutex_lock_interruptible_nested.
