Implement the new swapfile a_ops for NFS and hook up ->direct_IO. This
will set the NFS socket to SOCK_MEMALLOC and run socket reconnect under
PF_MEMALLOC as well as reset SOCK_MEMALLOC before engaging the protocol
->connect() method.PF_MEMALLOC should allow the allocation of struct socket and related
objects and the early (re)setting of SOCK_MEMALLOC should allow us to
receive the packets required for the TCP connection buildup.[jlayton@redhat.com: Restore PF_MEMALLOC task flags in all cases]

tries to do a blocking commit. That commit can't succeed however without
a connected socket, so we deadlock.Fix this by setting PF_FSTRANS on the workqueue task prior to doing the
socket allocation, and having nfs_release_page check for that flag when
deciding whether to do a commit call. Also, set PF_FSTRANS
unconditionally in rpc_async_schedule since that function can also do
allocations sometimes.Signed-off-by: Jeff Layton

to reduce hash collision probabilities in fq_codel (and other

by David Laight, as existing hash was ignoring most of them.Use it in sunrpc and use more bit shuffling, using hash_32().

The patch "SUNRPC: Add rpcauth_list_flavors()" introduces a new error

The gss_mech_list_pseudoflavors() function provides a list of
currently registered GSS pseudoflavors. This list does not include
any non-GSS flavors that have been registered with the RPC client.
nfs4_find_root_sec() currently adds these extra flavors by hand.Instead, nfs4_find_root_sec() should be looking at the set of flavors
that have been explicitly registered via rpcauth_register(). And,
other areas of code will soon need the same kind of list that
contains all flavors the kernel currently knows about (see below).Rather than cloning the open-coded logic in nfs4_find_root_sec() to
those new places, introduce a generic RPC function that generates a
full list of registered auth flavors and pseudoflavors.A new rpc_authops method is added that lists a flavor's
pseudoflavors, if it has any. I encountered an interesting module
loader loop when I tried to get the RPC client to invoke
gss_mech_list_pseudoflavors() by name.This patch is a pre-requisite for server trunking discovery, and a
pre-requisite for fixing up the in-kernel mount client to do better
automatic security flavor selection.Signed-off-by: Chuck Lever

Entries that are in a sunrpc cache but are not valid should be reported
with a leading '#' so they look like a comment.
Commit d202cce8963d9 (sunrpc: never return expired entries in sunrpc_cache_lookup)
broke this for expired entries.This particularly applies to entries that have been replaced by newer entries.
sunrpc_cache_update sets the expiry of the replaced entry to '0', but it
remains in the cache until the next 'cache_clean'.
The result is that if youecho 0 2000000000 1 0 > /proc/net/rpc/auth.unix.gid/channel
several times, then
cat /proc/net/rpc/auth.unix.gid/content
It will display multiple entries for the one uid, which is at least confusing:
#uid cnt: gids...
0 1: 0
0 1: 0
0 1: 0With this patch, expired entries are marked as comments so you get
#uid cnt: gids...
0 1: 0
# 0 1: 0
# 0 1: 0These expired entries will never be seen by cache_check() as they are always
*after* a non-expired entry with the same key - so the extra check is only
needed in c_show()Signed-off-by: NeilBrown

Pull NFS client updates from Trond Myklebust:
"New features include:
- Rewrite the O_DIRECT code so that it can share the same coalescing
and pNFS functionality as the page cache code.
- Allow the server to provide hints as to when we should use pNFS,
and when it is more efficient to read and write through the
metadata server.
- NFS cache consistency updates:
* Use the ctime to emulate a change attribute for NFSv2/v3 so that
all NFS versions can share the same cache management code.
* New cache management code will only look at the change attribute
and size attribute when deciding whether or not our cached data
is still valid or not.
* Don't request NFSv4 post-op attributes on writes in cases such as
O_DIRECT, where we don't care about data cache consistency, or
when we have a write delegation, and know that our cache is still
consistent.
* Don't request NFSv4 post-op attributes on operations such as
COMMIT, where there are no expected metadata updates.
* Don't request NFSv4 directory post-op attributes in cases where
the operations themselves already return change attribute
updates: i.e. operations such as OPEN, CREATE, REMOVE, LINK and
RENAME.
- Speed up 'ls' and friends by using READDIR rather than READDIRPLUS

- Improve the code sharing between NFSv2/v3 and v4 mounts
