Hello, Linus. libata fixes for v3.13-rc5. There's one interseting commit - "libata, freezer: avoid block device removal while system is frozen". It's an ugly hack working around a deadlock condition between driver core resume and block layer device removal paths through freezer which was made more reproducible by writeback being converted to workqueue some releases ago. The bug has nothing to do with libata but it's just an workaround which is easy to backport. After discussion, Rafael and I seem to agree that we don't really need kernel freezables - both kthread and workqueue. There are few specific workqueues which constitute PM operations and require freezing, which will be converted to use workqueue_set_max_active() instead. All other kernel freezer uses are planned to be removed, followed by the removal of kthread and workqueue freezer support, hopefully. Others are device-specific fixes. The most notable is the addition of NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro M500 SSDs which otherwise suffers data corruption.
