[v2,0/6] btrfs: simple quotas fstests

Message

Boris Burkov Sept. 27, 2023, 11:07 p.m. UTC

Add new tests (btrfs/400 for now, but intend to grab a real number
before the last version)

Also made modifications for passing existing qgroups tests when possible
and for passing all tests with simple quota enabled via mkfs and with
squota-aware `btrfs check`. Since this required reading sysfs files of
scratch fses, did a bit of refactoring to make those checks target a
device rather than assuming TEST_DEV.

btrfs/400 depends on the kernel patchset:
https://lore.kernel.org/linux-btrfs/[e-mail]/
and the btrfs-progs patchset:
https://lore.kernel.org/linux-btrfs/[e-mail]/
(and config appropriate binaries to use squota-aware versions)
