commit 7614209736fbc4927584d4387faade4f31444fce upstream.
CEPH_OSDMAP_FULL/NEARFULL aren't set since mimic, so we need to consult
per-pool flags as well. Unfortunately the backwards compatibility here
is lacking:
- the change that deprecated OSDMAP_FULL/NEARFULL went into mimic, but
was guarded by require_osd_release >= RELEASE_LUMINOUS
- it was subsequently backported to luminous in v12.2.2, but that makes
no difference to clients that only check OSDMAP_FULL/NEARFULL because
require_osd_release is not client-facing -- it is for OSDs
Since all kernels are affected, the best we can do here is just start
checking both map flags and pool flags and send that to stable.
These checks are best effort, so take osdc->lock and look up pool flags
just once. Remove the FIXME, since filesystem quotas are checked above
and RADOS quotas are reflected in POOL_FLAG_FULL: when the pool reaches
its quota, both POOL_FLAG_FULL and POOL_FLAG_FULL_QUOTA are set.
