sunrpc: add rpc_count_iostats_idx

2015-02-03T19:06:38+00:00

Add a call to tally stats for a task under a different statsidx than
what's contained in the task structure.

This is needed to properly account for pnfs reads/writes when the
DS nfs version != the MDS version.

SUNRPC: serialize iostats updates

2014-11-25T21:22:15+00:00

Occasionally mountstats reports a negative retransmission rate.
Ensure that two RPCs completing concurrently don't confuse the sums
in the transport's op_metrics array.

Since pNFS filelayout can invoke rpc_count_iostats() on another
transport from xprt_release(), we can't rely on simply holding the
transport_lock in xprt_release(). There's nothing for it but hard
serialization. One spin lock per RPC operation should make this as
painless as it can be.

SUNRPC: Deprecate rpc_client->cl_protname

2013-08-30T13:19:34+00:00

It just duplicates the cl_program->name, and is not used in any fast
paths where the extra dereference will cause a hit.

procfs: new helper - PDE_DATA(inode)

2013-04-09T18:13:32+00:00

The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data.  Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

SUNRPC: Use RCU to dereference the rpc_clnt.cl_xprt field

2012-03-02T20:36:38+00:00

A migration event will replace the rpc_xprt used by an rpc_clnt.  To
ensure this can be done safely, all references to cl_xprt must now use
a form of rcu_dereference().

Special care is taken with rpc_peeraddr2str(), which returns a pointer
to memory whose lifetime is the same as the rpc_xprt.

SUNRPC: register service stats /proc entries in passed network namespace context

2012-02-01T00:28:18+00:00

This patch makes it possible to create NFSd program entry ("/proc/net/rpc/nfsd")
in passed network namespace context instead of hard-coded "init_net".

SUNRPC: Simplify rpc_alloc_iostats by removing pointless local variable

2010-11-16T16:58:51+00:00

Hi,

We can simplify net/sunrpc/stats.c::rpc_alloc_iostats() a bit by getting
rid of the unneeded local variable 'new'.

Please CC me on replies.
