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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
