Prev: mm: Check for an empty VMA list in rmap_walk_anon
Next: 2.6.33-rc8 regression on i915: resume from hibernate locks up every 2nd time
From: Thomas Gleixner on 17 Feb 2010 13:50
The following series contains the following changes:

- fix the last users of the oldstyle seqlock initializer

- implement raw_seqlock (for seqlocks which need a raw_spinlock in
preempt-rt

- convert xtime_lock to raw_seqlock and fix up all users

- convert x86 vsyscall gtod seqlock to raw_seqlock

The patches have been used in the preempt-rt tree for quite a while
and are a defacto NOP change for mainline, but merging them takes off
the burden from preempt-rt.

Please review and comment.

Thanks,

tglx
