Hi,
the errors at the end of this mail come from one of my test boxes booted
with latest Linus:
8f4dd16603ce ("Merge branch 'akpm' (patches from Andrew)")
+ tip/master.
A second boot into the same kernel says:
[ 5.427329] EXT4-fs (sda5): warning: mounting fs with errors, running e2fsck is recommended
[ 5.435681] EXT4-fs (sda5): mounted filesystem with ordered data mode. Quota mode: disabled.
...
[ 316.621377] EXT4-fs (sda5): error count since last fsck: 14
[ 316.621645] EXT4-fs (sda5): initial error at time 1651146136: ext4_update_backup_sb:165
[ 316.621948] EXT4-fs (sda5): last error at time 1651146136: ext4_update_backup_sb:165
And it used to work fine with rc3:
EXT4-fs (sda5): mounted filesystem with ordered data mode. Quota mode: disabled.
so before I go and fsck the partition, I thought I should report it
first - maybe something new in ext4 land is not behaving as it should...
And since rc3 I see:
$ git log --oneline v5.18-rc3.. fs/ext4/
c00c5e1d157b Merge tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

so there is something which just got applied...
