strparser: Add __strp_unpause and use it in ktls.
strp_unpause queues strp_work in order to parse any messages that arrived while the strparser was paused. However, the process invoking strp_unpause could eagerly parse a buffered message itself if it held the sock lock. __strp_unpause is an alternative to strp_pause that avoids the scheduling overhead that results when a receiving thread unpauses the strparser and waits for the next message to be delivered by the workqueue thread. This patch more than doubled the IOPS achieved in a benchmark of NBD traffic encrypted using ktls. Signed-off-by: Doron Roberts-Kedes <doronrk@fb.com> Signed-off-by: David S.
