Subject[PATCH 5.1 110/128] ext4: avoid panic during forced reboot due to aborted journal
Date
From: Jan Kara <jack@suse.cz>

commit 2c1d0e3631e5732dba98ef49ac0bec1388776793 upstream.

Handling of aborted journal is a special code path different from
standard ext4_error() one and it can call panic() as well. Commit
1dc1097ff60e ("ext4: avoid panic during forced reboot") forgot to update
this path so fix that omission.
