Revision e523a29c4f2703bdb98f68ce1bb256e259fd8d5f authored by Stefan Bühler on 19 April 2019, 09:57:44 UTC, committed by Jens Axboe on 22 April 2019, 17:00:55 UTC
A read memory barrier is required between reading SQ tail and reading the actual data belonging to the SQ entry. Userspace needs a matching write barrier between writing SQ entries and updating SQ tail (using smp_store_release to update tail will do).
