Overall, the aim of this patch is to change the result of an nfs
op depending on whether the underlying volume is up or down
as notified by CHILD_UP and CHILD_DOWN events.
This patch contains three intertwined changes:
o Only when the lookup on the root of a volume is successful does gnfs now
export the subvolume. Till now the result of the lookup was not used to
determine whether we should export that volume. Not accounting for root lookup
failure resulted in ESTALEs on first access because some children of distribute
were down at the time of the root lookup.
o Only when lookups on all the subvolumes have succeeded are
these exports enabled through NFS.
o When a child of say distribute goes down, on CHILD_DOWN event nfs will
ignore all incoming requests from the client because ignoring these
will prevent ESTALEs for those requests and in the hope that ignoring the
requests will make the client retransmit. There are risks in this approach
absent the DRC but we're willing to live with that for now.
When a child goes down, the mount exports list will continue to show it
but mount requests will be denied.

- incorporate usage of uuid (gfid) as the key for finding inodes
- deprecate inode number/generation number based inode_get
- undo code specific to generation numbers (attic list etc.)

This is plain wrong. this must always be the xlator that receives the callback.
Use cookie to access the child subvolume on which the fop was issued.

nfsx has followed traditional approach of exporting whole volumes
as NFS exports. The Platform requires and some users have approached us for
introducing exports of only specific directories instead of full Gluster
volumes. This commit introduces this support through two nfsx options:
Option 1:
=========
option nfs3.<volume-name>.export-dir <subdir1-in-vol>,<subdir2-in-vol>,..<subdirN-in-vol>
export-dir will allow the export of a particular dir as a single export
by itself. For eg.:
volume posix
type storage/posix
option directory /export/
end-volume
volume posix-ac
type features/access-control
subvolumes posix
end-volume
volume nfs
type nfs/server
subvolumes posix-ac
option rpc-auth.addr.allow *
option nfs3.posix-ac.export-dir /homes/shehjart
end-volume
A comma separate list of sub-directories will set up those dirs as separated exports.
At the nfs client, the mount command will be:
$ mount <nfsserver>:/posix-ac/homes/shehjart /mnt
Option 2:
=========
option nfs3.<volume-name>.export-volumes <on|off>
There can be situations where users only want the directory level
exports and require that volume exports be completely disabled. The
above option allows us to do this. By default, volume exports are
enabled. From the earlier example, replacing <volume-name> with
posix-ac, will disable mounting of the posix-ac volume as a whole.

The current design of the interaction between the generic NFS layer and the
protocol handlers like mount3 and nfs3 is such that it does not allow using a
single volume file which contains the nfs/server and the protocol/server.
This is because the common nfs-fops layer assumes that ctx->top is always the
nfs/server. This is wrong. The fops layer needs access to top because top or
rather the generic NFS xlator's private state has a mem-pool. The fops layer
needs this mem-pool to get memory for storing per-fop state. Since the fops
layer cannot anymore take ctx->top be the nfs/server, all layers need to start
passing the nfs/server xlator_t right down to the fops layer.
I am also taking this chance to remove the synchronous equivalents of the fops
and also remove the dirent caching directory operations.
