--- Comment #34 from Bart Van Assche (bvanassche@....org) ---
I hit filesystem corruption with a desktop system running openSUSE Tumbleweed,
kernel v4.19.3 and ext4 on top of a SATA SSD with scsi_mod.use_blk_mq=Y in
/proc/cmdline. Discard was not enabled in /etc/fstab. After having enabled
fsck.mode=force the following appeared in the system log after a reboot:

/dev/sda2: Inode 12190197 extent tree (at level 2) could be narrower.  IGNORED.
