Subject: [PATCH 00/37] cputime: Convert core use of cputime_t to nsecs v3
Date: Sun, 22 Jan 2017 19:19:36 +0100	[thread overview]
Message-ID: <1485109213-8561-1-git-send-email-fweisbec@gmail.com> (raw)

Summary of this patchset in v1 (actually v2 as the v1 got posted 2 years
ago): https://lkml.org/lkml/2016/11/17/583

Changes in this version:

* Rebase against latest cputime changes (vtime accumulation and accounting
  delayed on tick and context switch)

* Fix leaking cputime remainder on s390

* Fix build errors

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	cputime/nsecs-v3

HEAD: 358818bd88b82c22bf3d45f82ba30ced534e3cd2

Thanks,
	Frederic
