Revision e91455bad5cff40a8c232f2204a5104127e3fec2 authored by Jan Kara on 07 August 2019, 09:36:47 UTC, committed by Jens Axboe on 08 August 2019, 13:37:03 UTC
Commit 89e524c04fa9 ("loop: Fix mount(2) failure due to race with
LOOP_SET_FD") converted blkdev_get() to use the new helpers for
finishing claiming of a block device. However the conversion botched the
error handling in blkdev_get() and thus the bdev has been marked as held
even in case __blkdev_get() returned error. This led to occasional
warnings with block/001 test from blktests like:
kernel: WARNING: CPU: 5 PID: 907 at fs/block_dev.c:1899 __blkdev_put+0x396/0x3a0
Correct the error handling.
