nfsd4_path() does both; caller expects to get NFS protocol error out it if

Congestion is a backing-dev concept, not a queue concept.
The blk_* congestion functions are retained, as wrappers around the core

This proper layering is needed so that NFS can cleanly use the congestion
functions, and so that CONFIG_BLOCK=n actually links.

When IO error happens on metadata buffer, buffer is freed from memory and

solve the problem by introducing a pointer to associated address space into
the buffer_head. When a buffer is removed from a list of metadata buffers
associated with an address space, IO error is transferred from the buffer to
the address space, so that fsync can later report it.

It is possible for the ->fopen callback from lockd into nfsd to find that an
answer cannot be given straight away (an upcall is needed) and so the request
has to be 'dropped', to be retried later. That error status is not currently
propagated back.
So:
Change nlm_fopen to return nlm error codes (rather than a private
protocol) and define a new nlm_drop_reply code.
Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply
when this error comes back.
Cause svc_process to drop a request which returns a status of
rpc_drop_reply.

When an nfs server shuts down, lockd needs to release all the locks even
though the client still holds them.
It should therefore not 'unmonitor' the clients, so that the files in nfs/sm
will still be there when the nfs server restarts, so that those clients will
be told to reclaim their locks.
However the hosts are fully unmonitored, so statd may well remove the files.
lockd has a test for 'sm_sticky' and avoid the unmonitor call if it is set,
but it is currently not set.
So set it when tearing down lockd.

If a client creates a file using an open which sets the mode to 000, or if a
chmod changes permissions after a file is opened, then situations may arise
where an NFS client knows that some IO is permitted (because a process holds
the file open), but the NFS server does not (because it doesn't know about the
open, and only sees that the IO conflicts with the current mode of the file).
As a hack to solve this problem, NFS servers normally allow the owner to
override permissions on IO. The client can still enforce correct
permissions-checking on open by performing an explicit access check.
In NFSv4 the client can rely on the explicit on-the-wire open instead of an
access check.
Therefore we should not be allowing the owner to override permissions on an
over-the-wire open!
However, we should still allow the owner to override permissions in the case
where the client is claiming an open that it already made either before a
reboot, or while it was holding a delegation.

Fuse considered it an error (EIO) if lookup returned a directory inode, to
which a dentry already refered. This is because directory aliases are not
allowed.
But in a network filesystem this could happen legitimately, if a directory is
moved on a remote client. This patch attempts to relax the restriction by
trying to first evict the offending alias from the cache. If this fails, it
still returns an error (EBUSY).
A rarer situation is if an mkdir races with an indenpendent lookup, which
finds the newly created directory already moved. In this situation the mkdir
should return success, but that would be incorrect, since the dentry cannot be
instantiated, so return EBUSY.
Previously checking for a directory alias and instantiation of the dentry
weren't done atomically in lookup/mkdir, hence two such calls racing with each
other could create aliased directories. To prevent this introduce a new
per-connection mutex: fuse_conn->inst_mutex, which is taken for instantiations
with a directory inode.

Fuse didn't always call i_size_write() with i_mutex held which caused rare
hangs on SMP/32bit. This bug has been present since fuse-2.2, well before
being merged into mainline.
The simplest solution is to protect i_size_write() with the per-connection
spinlock. Using i_mutex for this purpose would require some restructuring of
the code and I'm not even sure it's always safe to acquire i_mutex in all
places i_size needs to be set.
Since most of vmtruncate is already duplicated for other reasons, duplicate
the remaining part as well, making all i_size_write() calls internal to fuse.
Using i_size_write() was unnecessary in fuse_init_inode(), since this function
is only called on a newly created locked inode.
Reported by a few people over the years, but special thanks to Dana Henriksen
who was persistent enough in helping me debug it.
