Since thread_group worker and raid5d kthread are not in sync, if worker writes stripe before raid5d then requests will be waiting for issue_pendig. Issue observed when building raid5 with ext4, in some build runs jbd2 would get hung and requests were waiting in the HW engine waiting to be issued. Fix this by adding a call to async_tx_issue_pending_all in the raid5_do_work. Signed-off-by: NOfer Heifetz <oferh@marvell.com> Cc: stable@vger.kernel.org Signed-off-by: NShaohua Li <shli@fb.com>
