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.
