If the mountpoint path given to glusterfs is not an absolute path, convert it to
an absolute path by concatenating it with the curren working directory.
This prevents cases, where in gluster cannot perform clean unmounts when mount

In fuse upon graph changes fds were being migrated to the new graph.
It was done by taking all the fds from the fdtable in a structure and then
migrating each fd in the structure to the new graph. But after the fds
are migrated the structure which had the fds within it (that is refed fds)
was being freed without unrefing the fds, thus leading to a fd leak.

The purpose of this patch is to let protocol/client know when its transports can
be disconnected, without application running on gluster mount noticing any
effects of graph switch.
In order to do this, we migrate all fds and blocked locks to new graph.
Once this migration is complete and there are no in-transit frames as viewed
by fuse-bridge, we send a PARENT_DOWN event to its children. protocol/client
on receiving this event, can disconnect up its transports.

Currently(with out this patch), on a disconnect the server cleans up
the transport which inturn closes the fd's and releases the locks acquired on
those fd's by that client. On a reconnect, client just reopens the fd's but
doesn't reacquire the locks. The application that had previously acquired
the locks still is under the assumption that it is the owner of those locks
which might have been granted to other clients(if they request) by the server
leading to data corruption.
This patch allows the client to reacquire the fcntl locks (held on the fd's)
during client-server handshake.
* The server identifies the client via process-uuid-xl (which is a combination
of uuid and client-protocol name, it is assumed to be unique) and lk-version
number.
* The client maintains a list of process-uuid-xl, lk-version pair for each
accepted connection. On a connect, the server traverses the list for a
matching pair, if a matching pair is not found the the server returns
lk-version with value 0, else it returns the lk-version it has in store.
* On a disconnect, the server and client enter grace period, and on the
completion of the grace period, the client bumps up its lk-version number
(which means, it will reacquire the locks the next time) and the server will
distroy the connection. If reconnection happens within the grace period, the
server will find the matching (process-uuid-xl, lk-version) pair in its list
which guarantees that the fd's and there corresponding locks are still valid
for this client.
Configurable options:
To set grace-timeout, the following options are
option server.grace-timeout value
option client.grace-timeout value
To enable or disable the lk-heal,
option lk-heal [on|off]
gluster volume set command can be used to configurable options

1. What
--------
This change introduces an infrastructure change in the filesystem
which lets filesystem operation address objects (inodes) just by its
GFID. Thus far GFID has been a unique identifier of a user-visible
inode. But in terms of addressability the only mechanism thus far has
been the backend filesystem path, which could be derived from the
GFID only if it was cached in the inode table along with the entire set
of dentry ancestry leading up to the root.
This change essentially decouples addressability from the namespace. It
is no more necessary to be aware of the parent directory to address a
file or directory.
2. Why
-------
The biggest use case for such a feature is NFS for generating
persistent filehandles. So far the technique for generating filehandles
in NFS has been to encode path components so that the appropriate
inode_t can be repopulated into the inode table by means of a recursive
lookup of each component top-down.
Another use case is the ability to perform more intelligent self-healing
and rebalancing of inodes with hardlinks and also to detect renames.
A derived feature from GFID filehandles is anonymous FDs. An anonymous FD
is an internal USABLE "fd_t" which does not map to a user opened file
descriptor or to an internal ->open()'d fd. The ability to address a file
by the GFID eliminates the need to have a persistent ->open()'d fd for the
purpose of avoiding the namespace. This improves NFS read/write performance
significantly eliminating open/close calls and also fixes some of today's
limitations (like keeping an FD open longer than necessary resulting
in disk space leakage)
3. How
-------
At each storage/posix translator level, every file is hardlinked inside
a hidden .glusterfs directory (under the top level export) with the name
as the ascii-encoded standard UUID format string. For reasons of performance
and scalability there is a two-tier classification of those hardlinks
under directories with the initial parts of the UUID string as the directory
names.
For directories (which cannot be hardlinked), the approach is to use a symlink
which dereferences the parent GFID path along with basename of the directory.
The parent GFID dereference will in turn be a dereference of the grandparent
with the parent's basename, and so on recursively up to the root export.
4. Development
---------------
4a. To leverage the ability to address an inode by its GFID, the technique is
to perform a "nameless lookup". This means, to populate a loc_t structure as:
loc_t {
pargfid: NULL
parent: NULL
name: NULL
path: NULL
gfid: GFID to be looked up [out parameter]
inode: inode_new () result [in parameter]
}
and performing such lookup will return in its callback an inode_t
populated with the right contexts and a struct iatt which can be
used to perform an inode_link () on the inode (without a parent and
basename). The inode will now be hashed and linked in the inode table
and findable via inode_find().
A fundamental change moving forward is that the primary fields in a
loc_t structure are now going to be (pargfid, name) and (gfid) depending
on the kind of FOP. So far path had been the primary field for operations.
The remaining fields only serve as hints/helpers.
4b. If read/write is to be performed on an inode_t, the approach so far
has been to: fd_create(), STACK_WIND(open, fd), fd_bind (in callback) and
then perform STACK_WIND(read, fd) etc. With anonymous fds now you can do
fd_anonymous (inode), STACK_WIND (read, fd). This results in great boost
in performance in the inbuilt NFS server.
5. Misc
-------
The inode_ctx_put[2] has been renamed to inode_ctx_set[2] to be consistent
with the rest of the codebase.
