nfsd: make fs/nfsd/vfs.h for common includes None of this stuff is used outside nfsd, so move it out of the common linux include directory. Actually, probably none of the stuff in include/linux/nfsd/nfsd.h really belongs there, so later we may remove that file entirely. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

nfsd: distinguish functions of NFSD_MAY_* flags Most of the NFSD_MAY_* flags actually request permissions, but over the years we've accreted a few that modify the behavior of the permission or open code in other ways. Distinguish the two cases a little more. In particular, allow the shortcut at the start of nfsd_permission to ignore the non-permission-requesting bits. Signed-off-by: J.

nfsd: filter readdir results in V4ROOT case As with lookup, we treat every boject as a mountpoint and pretend it doesn't exist if it isn't exported. The preexisting code here is confusing, but I haven't yet figured out how to make it clearer. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

nfsd41: make sure nfs server process OPEN with EXCLUSIVE4_1 correctly The NFS server uses nfsd_create_v3 to handle EXCLUSIVE4_1 opens, but that function is not prepared to handle them.

nfsd: minor nfsd read api cleanup Christoph points that the NFSv2/v3 callers know which case they want here, so we may as well just call the file=NULL case directly instead of making this conditional. Cc: Christoph Hellwig <hch@infradead.org> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
