[PATCH v2 0/2] getrusage: use sig->stats_lock

[Oleg Nesterov]

Andrew,

this series replaces

	getrusage-move-thread_group_cputime_adjusted-outside-of-lock_task_sighand.patch
	getrusage-use-sig-stats_lock.patch

in mm-nonmm-unstable.

The patches are same, I only tried to improve the changelogs as we discussed.

Dylan, do you have something to add?

Oleg.
