I indeed committed 4d2aa150769b ("vhost: remove check around mutex init"); and it contained a hunk for vhost_driver_register(). I applied this patch against the tip of the main; from what I saw, there is no overlap with 4d2aa150769b ("vhost: remove check around mutex init"). It looks 4d2aa150769b ("vhost: remove check around mutex init") came up first, because I was the last person who edited the file. The tags should be rather these ones: Fixes: 0adb8eccc6a6 ("vhost: add VDUSE device creation and destruction") Fixes: 78b2e3bae1af ("vhost: fix initialization") Fixes: 64ab701c3d1e ("vhost: add vhost-user client mode") Fixes: 8f972312b8f4 ("vhost: support vhost-user") Does my reasoning make sense? Let me know. :) For my understanding; now that 4d2aa150769b ("vhost: remove check around mutex init") needs a fix, is there a way by which I could have detect the regression? Your help will be much appreciated, Ariel
