Hello Jens, This patch series reworks the blk_mq_mark_tag_wait() implementation and also fixes a race condition in that function. Please consider these two patches for kernel v4.16. Thanks, Bart. Changes compared to v3: - Reworked patch 1/2 such that it uses if (...) ...; ... instead of if (...) ... else ... as proposed by Jens. Changes compared to v1: - Split a single patch into two patches to make reviewing easier. - The race fix does no longer use prepare_to_wait() / finish_wait().
