Keith Busch 4cc06521ee NVMe: add sysfs and ioctl controller reset ... We need the ability to perform an nvme controller reset as discussed on the mailing list thread: http://lists.infradead.org/pipermail/linux-nvme/2015-March/001585.html This adds a sysfs entry that when written to will reset perform an NVMe controller reset if the controller was successfully initialized in the first place. This also adds locking around resetting the device in the async probe method so the driver can't schedule two resets. Signed-off-by: Keith Busch <keith.busch@intel.com> Cc: Brandon Schultz <brandon.schulz@hgst.com> Cc: David Sariel <david.sariel@pmcs.com> Updated by Jens to: 1) Merge this with the ioctl reset patch from David Sariel. The ioctl path now shares the reset code from the sysfs path. 2) Don't flush work if we fail issuing the reset. Signed-off-by: Jens Axboe <axboe@fb.com>		2015-06-05 10:30:08 -06:00
