Ingo,
Coming next are 3 patches to your mutex code that I'd like you to
consider. They express my last requests about mutexes.
The first patch is a resent of my trylock rework to allow for a pure
xchg based implementation.
The second one gives architectures the ability to make lock/unlock
fastpaths inlined. As explained in another mail this is almost always
beneficial on ARM.
And the last patch makes mutex_is_locked() always inlined since I can't
find a reason why it wouldn't be beneficial to do so, even on x86.
I hope we can agree on them so that I could go back hiding behind
ARM-specific part of the kernel again. :-)
Nicolas
