debug patch for checking source bio's segments
The bisected commit should be a false positive, and it is simple and correct. 0028 should be offset of 'bio->bi_iter.bi_size', so looks 'mbio' cloned from bio_clone_mddev() is NULL, could you test the attached patch? Then reproduce and post the log? Thanks, Does this problem still show up in Linux v5.5 or v5.6-rc ? Thanks. Coly Li |
