Hello,
syzbot has tested the proposed patch and the reproducer did not trigger crash:
Reported-and-tested-by: syzbot+67e4f16db666b1c82...@syzkaller.appspotmail.com
Tested on:
commit: 54d3adbc ext4: save all error info in save_error_info() an..
git tree:
#syz test https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git dev
I'm curious why this is only showing up as failing on next-next.
Let's see if it fails on the ext4.git tree.
>From the bisect logs syzbot is able to repro on all of v5.x and
v4.20.0. However, I'm not able to repro it
