nfsd: allow nfsv3 readdir request to be larger.
nfsd currently reports the NFSv3 dtpref FSINFO parameter to be PAGE_SIZE, so NFS clients will typically ask for one page of directory entries at a time. This is needlessly restrictive as nfsd can handle larger replies easily. Also, a READDIR request (but not a READDIRPLUS request) has the count size clipped to PAGE_SIE, again unnecessary. This patch lifts these limits so that larger readdir requests can be used. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
