[PATCH v2 0/2] add test for zone_gc_low_space attribute writes

Adds a test for zone_gc_low_space attribute writes and some helpers to
go along with that.

The new test will fail currently, but i've submitted a fix:
https://lore.kernel.org/linux-xfs/[email protected]/

v2:
- factored out useful helpers to common/xfs
- style fixes suggested by Christoph
- added a check that the scratch rt device is zoned before reading zone
  capacity

v1:

Hans Holmberg (2):
  xfs/647: turn rt dev block device lookup into a common helper
  xfs: test that zone_gc_low_space writes start gc for rw fses
