Revision 11ba820bf163e224bf5dd44e545a66a44a5b1d7a authored by Jens Axboe on 16 January 2020, 04:51:17 UTC, committed by Jens Axboe on 16 January 2020, 04:51:17 UTC
A previous commit moved the locking for the async sqthread, but didn't
take into account that the io-wq workers still need it. We can't use
req->in_async for this anymore as both the sqthread and io-wq workers
set it, gate the need for locking on io_wq_current_is_worker() instead.
Fixes: 8a4955ff1cca ("io_uring: sqthread should grab ctx->uring_lock for submissions")
