Clean up: some fops use NFSDBG_FILE, some use NFSDBG_VFS. Let's use NFSDBG_FILE for all fops, and consistently report file names instead of inode numbers. Signed-off-by: NChuck Lever <chuck.lever@oracle.com> Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

invalidate_inode_pages2_range() takes page offset arguments, not byte ranges. Another thought is that individual pages might perhaps get evicted by VM pressure, in which case we might perhaps want to re-read not only the evicted page, but all subsequent pages too (in case the server returns more/less data per page so that the alignment of the next entry changes). We should therefore remove the condition that we only do this on page->index==0. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

If we depend on the inodes for writeability, we will not catch the r/o mounts when implemented. This patches uses __mnt_want_write(). It does not guarantee that the mount will stay writeable after the check. But, this is OK for one of the checks because it is just for a printk(). The other two are probably unnecessary and duplicate existing checks in the VFS. This won't make them better checks than before, but it will make them detect r/o mounts.

The NFSv4 protocol allows clients to negotiate security protocols on the fly in the case where an administrator on the server changes the export settings and/or in the case where we may have a filesystem migration event. Instead of having the NFS client code cache credentials that are tied to a particular AUTH method it is therefore preferable to have a generic credential that can be converted into whatever AUTH is in use by the RPC client when the read/write/sillyrename/... is put on the wire. We do this by means of the new "generic" credential, which basically just caches the minimal information that is needed to look up an RPCSEC_GSS, AUTH_SYS, or AUTH_NULL credential.

As long as the directory contents haven't changed, we should just let the path walk proceed to cross the mountpoint. Apart from being an optimisation in the case of 'nohide' mountpoint traversals, it also fixes an issue with referrals: referral inodes don't have valid filehandles, so calling nfs_revalidate_inode() on them is a bug.

Ensure that readdir revalidates its data cache after blocking on sillyrename. Also fix a typo in nfs_do_call_unlink(): swap the ^= for an |=. The result is the same, since we've already checked that the flag is unset, but it makes the code more readable. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

lookup() and sillyrename() can race one another because the sillyrename() completion cannot take the parent directory's inode->i_mutex since the latter may be held by whoever is calling dput(). We therefore have little option but to add extra locking to ensure that nfs_lookup() and nfs_atomic_open() do not race with the sillyrename completion. If somebody has looked up the sillyrenamed file in the meantime, we just transfer the sillydelete information to the new dentry.
