[PATCH] nfsd4: fix fh_expire_type
We're returning NFS4_FH_NOEXPIRE_WITH_OPEN | NFS4_FH_VOL_RENAME for the
fh_expire_type attribute. This is incorrect:
1. The spec actually only allows NOEXPIRE_WITH_OPEN when
VOLATILE_ANY is also set.
2. Filehandles for open files can expire, if the file is removed
and there is a reboot.
3. Filehandles are only volatile on rename in the nosubtree check
case.
Unfortunately, there's no way to indicate that we only expire on remove. So
our only choice is FH4_VOLATILE_ANY. Although it's redundant, we also set
FH4_VOL_RENAME in the subtree check case, since subtreecheck does actually
cause problems in practice and it seems possibly useful to give clients some
way to distinguish that case.
Fix a mispelled #define while we're at it.
