Subject: [GIT PULL pm-next] freezer: fix various bugs and simplify implementation
Date: Sat, 20 Aug 2011 11:44:34 +0200	[thread overview]
Message-ID: <20110820094434.GA24151@htj.dyndns.org> (raw)

Hello, Rafael.

Please consider pulling from the following branch to receive freezer
fixes and simplifications patchset[1].  The only changes from the
posting are addition of acked-by's, minor patch description updates
and rebase on top of pm-next (af0fa9cb79 "PM / Hibernate: Include
storage keys in hibernation image on s390").

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git freezer

The HEAD should be 7b5b95b3f51a28ec008a295e5247436637220f41.  If
git.korg doesn't show it yet.  Please pull from master.korg.

  ssh://master.kernel.org/pub/scm/linux/kernel/git/tj/misc.git freezer

FYI, this patchset will cause a conflict with s390 TIF flag fix patch.
The conflict is trivial and Stephen should be able to handle it
without any problem.  Also, I'm planning on doing some further work on
cgroup freezer and then will try to bridge it with job control.  If
that plan fans out, I might ask Oleg to pull from the pm tree.  This
shouldn't matter too much either way but it *might* be a good idea to
keep this line of patches in a separate branch.

Thank you.
