Subject: [GIT PULL] timer fix

Linus,

Please pull the latest timer-fixes-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git timer-fixes-for-linus

This fixes the scheduler bug discussed in the:

 "2.6.39-rc4+: Kernel leaking memory during FS scanning, regression?"

lkml thread.

 Thanks,

	Ingo
