Subject: [PATCH v2 0/4] PM / Freezer: Fix the semantics of thaw_processes() and thaw_kernel_threads()
Date: Tue, 31 Jan 2012 04:44:11 +0530 [thread overview]
Message-ID: <20120130231342.11129.87187.stgit@srivatsabhat.in.ibm.com> (raw)
With the introduction of thaw_kernel_threads(), we can now finally fix the
semantics of thawing tasks, in such a way as to be just the opposite of
how tasks are frozen. This opens up some opportunities for code cleanup
as well. This patchset implements both of these improvements.
v2: Interchanged the ordering of patches 1 and 2 and transferred a small
comment between them. No code changes.

PM/Freezer: Use thaw_kernel_threads() in preparation for changes to thaw_processes()
PM/Freezer: Make thaw_processes() thaw only userspace tasks
PM/Hibernate: Thaw kernel threads in hibernation_snapshot() in error/test path
PM/Hibernate: Refactor and simplify freezer_test_done
