MD's rdev_set_badblocks() expects that badblocks_set() returns 1 if badblocks are disabled, otherwise, rdev_set_badblocks() will record superblock changes and return success in that case and md will fail to report an IO error which it should. This bug has existed since badblocks were introduced in commit 9e0e252a048b ("badblocks: Add core badblock management code").
