nfs, nfs3: Base volume access on CHILD-UP-DOWN event

2010-09-22T11:14:27+00:00

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.

nfs: Fine tune nfs_entry_loc_fill return values

2010-05-10T09:17:57+00:00

A previous change to this function introduced a regression
for exclusive creates. This patch fixes the regression by
bringing the return values in line with what the callers
expect in different situations of loc filling.

nfs: Handle failed parent loc filling

2010-05-08T13:37:29+00:00

Just because an inode_get for parent (ino, gen) returns a valid
inode_t does not meant that the inode_path(..in nfs_parent_inode_loc_fill..)
will return successfully. The failure of nfs_parent_inode_loc_fill was
not handled resulting in a NULL path being passed for the fop.
