which make the bufferlist can be full amount copied.

Some old bug (e.g., http://tracker.ceph.com/issues/20751) could
result in an UP+EXISTS osd having features==0. If that happens,
we shouldn't crash the mon, which (reasonably) does
if (osdmap.get_epoch()) {
if (osdmap.get_num_up_osds() > 0) {
assert(osdmap.get_up_osd_features() & CEPH_FEATURE_MON_STATEFUL_SUB);
check_subs();
}
}

the commit d406f228 in gperf implements a c11 feature used by a
recent change in rocksdb: 16e03882, which uses aligned_alloc().
and 16e03882 in rocksdb was merged after v5.7 was tagged, while
16e03882 in gperf was merged after v2.6.1 was tagged.
because aligned_alloc() is not implemented by tcmalloc until the
not-yet-released 2.6.2, if we call aligned_alloc() in an application
linked against tcmalloc, what gets called will be the glibc's
aligned_alloc(). but if we free() the memory chunk allocated by
aligned_alloc(), the tcmalloc's implementation kicks in, then
InvalidFree() is called, because the memory chunk being freed was
allocated by tcmalloc. in short, "mixing allocators", quote from
Dan Mick.
in rocksdb, aligned_alloc() is used if _ISOC11_SOURCE is defined, this
makes sense, because aligned_alloc() is a C11 function. we could avoid
using it by not defining _ISOC11_SOURCE. but as long as _GNU_SOURCE is
defined, glibc defines _ISOC11_SOURCE. and libstdc++ requires
_GNU_SOURCE, because it uses a fair amount of GNU extensions.

We now set full flag if a pool is currently running out of space and
set both full and full_no_quota flags if it is running out of quota.
Therefore the full_no_quota flag should be instead used to uniquely
identify whether we are running out of quota or not.

The fast dispatch refactor in 3cc48278bf
eliminated the osdmap subscription in the ms_fast_dispatch path, which
meant ops could reach a PG without having the latest map. In a cluster
with few osdmap updates, where the monitor fails to send a new map to
an osd (it tries one random osd), this can result in indefinitely
blocked requests.
Fix this by adding an OSDService mechanism for scheduling a new osdmap
subscription request.

By default, ceph-fuse uses side effect of 'dentry invalidation' to
trim kernel dcache if it runs on kernel < 3.18. The implemention of
kernel function d_invalidate() changed in 3.18 kernel, the method no
longer works for upstream kernel >= 3.18.
RHEL 3.10 kernel includes backport of patches that change implemention
of d_invalidate(). So checking kernel version to decide if 'dentry
invalidation' method works is unreliable.
