Usage: "glusterfs-defrag <MOUNTPOINT>"
there are new features added to distribute with this patch:
* bash# getfattr -n trusted.distribute.linkinfo <file>
Gives output in the format "<hostname>:<directory>", if there is a
linkfile present, where hostname is server, directory is backend
directory where the actual linkfile is present.
* bash# getfattr -n trusted.glusterfs.pathinfo <path>
Gives layout information if directory, and info about actual
location of file in backend servers, in the form of
'hostname:directory'. (TODO: should extend it to all xlators)
* bash# getfattr -n trusted.distribute.fix.layout <path>
scales out the directory layout in distribute, so when new
servers are added, layouts are fixed to include them.
* removed 'scale-n-defrag.sh' as its no more required.
* changed 'defrag.sh' to have a feature to specify target bricks,
so defrag happens to only those nodes. moved the file to
'glusterfs-defrag', which now gets installed to '${prefix}/bin'
* storage/posix:
takes new option 'hostname' so it can resolve to same hostname
given during 'gluster volume create'.
with 'trusted.glusterfs.pathinfo' posix returns the value in
'hostname:real_path' format.

Submitted-by: Krishna Srinivas <krishna@gluster.com>
NOTE: fixed compilation issues in posix.c introduced while merging
storage/posix polls for FS/kernel being functional by issuing
statvfs() call. In case statvfs expires the timer, storage/posix will
send CHILD_DOWN to upper translator. Ultimately this will cause
protocol/server to disconnect all clients connected and also cleans up
the data structures. Hence if soft lockup or other kernel bug causes
backend FS to hang, the clients will not be hung.

when posix_release is called. This avoids blocking the main server loop
due to close().

The janitor thread deletes all files and directories in
the "/" GF_REPLICATE_TRASH_DIR directory. This directory
is used by replicate self-heal to dump files and
directories it deletes.
This is needed because letting replicate walk the directory
tree and delete a directory and all its children is too racy.
Instead, replicate self-heal only does an atomic rename(),
and the janitor thread takes care of actually deleting them.

This feature enables exported directory containing different mountpoints.
With, 'option span-devices <n>' where n is number of different mountpoints
export directories can have, one can enable this feature. By default the
number will be 1, and the inode scaling won't come into picture.
