From: Filipe Manana <fdman...@suse.com>
Hi Chris,
Here follows two cleanups and a fix for an issue that leads to a logical
corruption in the extent tree, where we end up with file extent items in
subvolume trees that don't have a matching extent item and back reference
in the extent tree after a balance when qgroups are enabled. This is a
regression introduced in 4.7 by a fix for yet another regression caused
by the last qgroups rework. This has been hitting SLE and openSUSE users
and QA very badly, where transactions keep getting aborted when running
delayed references leaving the root filesystem in RO mode and nearly
unusable. If you think it's appropriate, please consider it for
the 4.9 kernel (I've also tagged it for stable).
And of course, the two cleanups can wait for the 4.10 merge window.
Thanks.
