Recent NFS v4.2 drafts have removed NFS4ERR_METADATA_NOTSUPP and reassigned the error code to NFS4ERR_UNION_NOTSUPP. I also add in the NFS4ERR_OFFLOAD_NO_REQS error code.

current_task appears to be x86-only, oops. Let's just delete this check entirely: Any developer that adds a new user without setting rq_task will get a crash the first time they test it. I also don't think there are normally any important locks held here, and I can't see any other reason why killing a server thread would bring the whole box down. So the effort to fail gracefully here looks like overkill. Reported-by: NStephen Rothwell <sfr@canb.auug.org.au> Fixes: 983c6844 "SUNRPC: get rid of the request wait queue" Signed-off-by: NJ.

One of our customer's application only needs file names, not file attributes. With directories having 10K+ inodes (assuming buffer cache has directory blocks cached having file names, but inode cache is limited and hence need eviction of older cached inodes), older inodes are evicted periodically. So if they keep on doing readdir(2) from NSF client on multiple directories, some directory's files are periodically removed from inode cache and hence new readdir(2) on same directory requires disk access to bring back inodes again to inode cache. As READDIRPLUS request fetches attributes also, doing getattr on each file on server, it causes unnecessary disk accesses. If READDIRPLUS on NFS client is returned with -ENOTSUPP, NFS client uses READDIR request which just gets the names of the files in a directory, not attributes, hence avoiding disk accesses on server. There's already a corresponding client-side mount option, but an export option reduces the need for configuration across multiple clients. This flag affects NFSv3 only. If it turns out it's needed for NFSv4 as well then we may have to figure out how to extend the behavior to NFSv4, but it's not currently obvious how to do that.

As of 8c7424cf "nfsd4: don't try to encode conflicting owner if low on space", we permit the server to process a LOCK operation even if there might not be space to return the conflicting lockowner, because we've made returning the conflicting lockowner optional. However, the rpc server still wants to know the most we might possibly return, so we need to take into account the possible conflicting lockowner in the svc_reserve_space() call here. Symptoms were log messages like "RPC request reserved 88 but used 108".

When creating a file that already exists in a read-only directory with O_EXCL, the NFSv3 server returns EACCES rather than EEXIST (which local files and the NFSv4 server return). Fix this by checking the MAY_CREATE permission only if the file does not exist. Since this already happens in do_nfsd_create, the check in nfsd3_proc_create can simply be removed.

Currently, we hold the state_lock when releasing the lease. That's potentially problematic in the future if we allow for setlease methods that can sleep. Move the nfs4_put_deleg_lease call out of the delegation unhashing routine (which was always a bit goofy anyway), and into the unlocked sections of the callers of unhash_delegation_locked.

Currently these fields are protected with the state_lock, but that doesn't really make a lot of sense. These fields are "private" to the nfs4_file, and can be protected with the more granular fi_lock. The fi_lock is already held when setting these fields. Make the code hold the fp->fi_lock when clearing the lease-related fields in the nfs4_file, and no longer require that the state_lock be held when calling into this function. To prevent lock inversion with the i_lock, we also move the vfs_setlease and fput calls outside of the fi_lock. This also sets us up for allowing vfs_setlease calls to block in the future. Finally, remove a redundant NULL pointer check. unhash_delegation_locked locks the fp->fi_lock prior to that check, so fp in that function must never be NULL.
