shadow_copy2_find_mount_point() does direct stat() calls locally while
trying to automatically detect the mount point. This cannot be always
true as there are virtual file systems like CephFS, GlusterFS etc.
without their share path locally available on the system. Instead use
the VFS interface to make the stat calls hit the underlying file system
irrespective of their local presence in the system.

GNU getopt(3) is by default non-POSIX compliant and accepts options after
positional arguments (unless forced with POSIXLY_CORRECT). This is not portable,
e..g., on FreeBSD. Put options first and then positional arguments.

A larger cache costs more per transaction, but makes a large number
of operations within a transaction faster. We expect to be dealing
with the latter case here, regardless of the batch_mode parameter
and the database size. 200000 is chosen because it is also used in
join and schemaupgrade, and should be sufficient in most cases.

The timestamp validation added as part of the fix for bug 15151 causes hard
failures for certain clients that seem to use a temporary timestamp initially
when creating files, changing in a later step.
Clamp invalid timestamps to the allowed range 0..UINT32_MAX if
"gpfs:clamp_invalid_times = yes" is set.

Store the set of open O_XXX flags as part of the referenced file-handle

Use singed int32_t for cached mount-entries reference counting. Define
helper function for inc/dec ref-count which also provides proper
logging. Prefer boolean return-value for 'cephmount_cache_remove' as
'int' is often used as error indicator within the context of libcephfs

Prefer a safe version of ceph_readdir, where the directory entry struct
is allocated by the caller. Use a dynamic-allocated 'struct dirent'

CLOSEDIR (or unlikely readdir error).

Provide early support for consuming yet to come libcephfs proxy[1] for
optimized resource utilization. For better control we make use of an
additional module specific option 'proxy' to specify the intent to load
proxy library. With the default value 'no' a regular cephfs connection
is established. There is also an 'auto' mode which can fall back to the
regular connection if proxy requirements are not met.

The important part is the INVALID_SID should not

We need to return the intact names array with the

if we would otherwise return NONE_MAPPED.
For SOME_NOT_MAPPED we need to ignore invalid sids
and just pretend they are not mapped.
