7663dacd92 nfsd: remove pointless paths in file headers
The new .h files have paths at the top that are now out of date.  While
we're here, just remove all of those from fs/nfsd; they never served any
purpose.

9a74af2133 nfsd: Move private headers to source directory
Lots of include/linux/nfsd/* headers are only used by
nfsd module. Move them to the source directory

341eb18446 nfsd: Source files #include cleanups
Now that the headers are fixed and carry their own wait, all fs/nfsd/
source files can include a minimal set of headers. and still compile just
fine.

This patch should improve the compilation speed of the nfsd module.

0a3adadee4 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.

1b7e0403c6 nfsd: register NFS_ACL with rpcbind
Modify the NFS server to register the NFS_ACL services with the rpcbind
daemon.  This allows the client to ping for the existence of the NFS_ACL
support via commands such as "rpcinfo -t <server> nfs_acl".

This patch also modifies the NFS_ACL support so that responses to
version 2 NULLPROC requests can be made.

The changelog for the patch which turned off this functionality
mentioned something about not registering the NFS_ACL as being part of
some tradition.  I can't find this tradition and the only other
implementation which supports NFS_ACL does register them with the
rpcbind daemon.

8837abcab3 nfsd: rename MAY_ flags
Rename nfsd_permission() specific MAY_* flags to NFSD_MAY_* to make it
clear, that these are not used outside nfsd, and to avoid name and
number space conflicts with the VFS.

[comment from hch: rename MAY_READ, MAY_WRITE and MAY_EXEC as well]

ac8587dcb5 knfsd: fix spurious EINVAL errors on first access of new filesystem
The v2/v3 acl code in nfsd is translating any return from fh_verify() to
nfserr_inval.  This is particularly unfortunate in the case of an
nfserr_dropit return, which is an internal error meant to indicate to
callers that this request has been deferred and should just be dropped
pending the results of an upcall to mountd.

Thanks to Roland <devzero@web.de> for bug report and data collection.

14d2b59e8c [PATCH] NFS3: Calculate 'w' a bit later in nfs3svc_encode_getaclres()
NFS3: Calculate 'w' a bit later in nfs3svc_encode_getaclres()
      This is a small performance optimization since we can return before
      needing 'w'. It also saves a few bytes of .text :
      Before:
           text    data     bss     dec     hex filename
           1632     140       0    1772     6ec fs/nfsd/nfs3acl.o
      After:
           text    data     bss     dec     hex filename
           1624     140       0    1764     6e4 fs/nfsd/nfs3acl.o

bc5fea4299 [PATCH] knfsd: register all RPC programs with portmapper by default
The NFSACL patches introduced support for multiple RPC services listening on
the same transport.  However, only the first of these services was registered
with portmapper.  This was perfectly fine for nfsacl, as you traditionally do
not want these to show up in a portmapper listing.

The patch below changes the default behavior to always register all services
listening on a given transport, but retains the old behavior for nfsacl
services.

4452435948 [PATCH] knfsd: Replace two page lists in struct svc_rqst with one
We are planning to increase RPCSVC_MAXPAGES from about 8 to about 256.  This
means we need to be a bit careful about arrays of size RPCSVC_MAXPAGES.

struct svc_rqst contains two such arrays.  However the there are never more
that RPCSVC_MAXPAGES pages in the two arrays together, so only one array is
needed.

The two arrays are for the pages holding the request, and the pages holding
the reply.  Instead of two arrays, we can simply keep an index into where the
first reply page is.

This patch also removes a number of small inline functions that probably
server to obscure what is going on rather than clarify it, and opencode the
needed functionality.

Also remove the 'rq_restailpage' variable as it is *always* 0.  i.e.  if the
response 'xdr' structure has a non-empty tail it is always in the same pages
as the head.

 check counters are initilised and incr properly
 check for consistant usage of ++ etc
 maybe extra some inlines for common approach

b7964c3d88 [PATCH] nfsd: check for read-only exports before setting acls
We must check for MAY_SATTR before setting acls, which includes checking
for read-only exports: the lower-level setxattr operation that
eventually sets the acl cannot check export-level restrictions.
