Subject: [PATCH 0/2] md: it panic after reshape from raid1 to raid5
Date: Thu,  9 Dec 2021 13:55:22 +0800	[thread overview]
Message-ID: <1639029324-4026-1-git-send-email-xni@redhat.com> (raw)

Hi all

After reshape from raid1 to raid5, it can panice when there are I/Os

The steps can reproduce this:
mdadm -CR /dev/md0 -l1 -n2 /dev/loop0 /dev/loop1
mdadm --wait /dev/md0
mkfs.xfs /dev/md0
mdadm /dev/md0 --grow -l5
mount /dev/md0 /mnt

These two patches fix this problem.

  Free r0conf memory when register integrity failed
  Move alloc/free acct bioset in to personality
