J. Bruce Fields bfa4b36525 nfsd: state.c should include current_stateid.h
OK, admittedly I'm mainly just trying to shut sparse up.

They're equivalent, but SEEK_SET is more informative...

Stanislav Kinsbursky e5f06f720e nfsd: make expkey cache allocated per network namespace context

as a parameter and thus loop over all networks was replaced by only one call
for ip map cache purge.

Stanislav Kinsbursky e3f70eadb7 Lockd: pass network namespace to creation and destruction routines
v2: dereference of most probably already released nlm_host removed in
nlmclnt_done() and reclaimer().

These routines are called from locks reclaimer() kernel thread. This thread
works in "init_net" network context and currently relays on persence on lockd
thread and it's per-net resources. Thus lockd_up() and lockd_down() can't relay
on current network context. So let's pass corrent one into them.

Stanislav Kinsbursky f890edbbef NFSd: remove hard-coded dereferences to name-to-id and id-to-name caches
These dereferences to global static caches are redundant. They also prevents
converting these caches into per-net ones. So this patch is cleanup + precursor
of patch set,a which will make them per-net.

Jeff Layton 33dcc481ed nfsd: don't use locks_in_grace to determine whether to call nfs4_grace_end
It's possible that lockd or another lock manager might still be on the
list after we call nfsd4_end_grace. If the laundromat thread runs
again at that point, then we could end up calling nfsd4_end_grace more
than once.

That's not only inefficient, but calling nfsd4_recdir_purge_old more
than once could be problematic. Fix this by adding a new global
"grace_ended" flag and use that to determine whether we've already
called nfsd4_grace_end.

J. Bruce Fields 9dc4e6c4d1 nfsd: don't fail unchecked creates of non-special files
Allow a v3 unchecked open of a non-regular file succeed as if it were a
lookup; typically a client in such a case will want to fall back on a
local open, so succeeding and giving it the filehandle is more useful
than failing with nfserr_exist, which makes it appear that nothing at
all exists by that name.

Similarly for v4, on an open-create, return the same errors we would on
an attempt to open a non-regular file, instead of returning
nfserr_exist.

This fixes a problem found doing a v4 open of a symlink with
O_RDONLY|O_CREAT, which resulted in the current client returning EEXIST.

Thanks also to Trond for analysis.
