flock and posix lock do not use process ID as owner identifier.
The process ID of who holds the lock is just for F_GETLK fcntl(2).
For linux kernel, File lock's owner identifier is the file pointer
through which the lock is requested.
The fix is do not take the 'pid_namespace' into consideration when
checking conflict locks. Also rename the 'pid' fields of struct
ceph_mds_request_args and struct ceph_filelock to 'owner', rename
'pid_namespace' fields to 'pid'.
The kclient counterpart of this patch modifies the flock code to
assign the file pointer to the 'owner' field of lock message. It
also set the most significant bit of the 'owner' field. We can use
that bit to distinguish between old and new clients.

The new MDS request is used for connecting a given inode to its
parent inode. It allows client to have efficient implementation of
get_rename() NFS export callback.

This constant was just added in the public header to match the
operations in rados.h, and was not included in a stable release yet.
NOP is misleading, since it's actually uninterpreted anywhere, and
using it would always return EIO from the OSD. It's not particularly
useful, so just remove it. Adding a cmpxattr with FAIL_OK is
equivalent.

dissector, it has been re-worked to bring into line with Wireshark
coding guidelines that aim to ensure portability. It currently only
decodes a handful of messages as test cases, it needs more work to make
it useful. See README.txt for a bit more background.
