[PATCH v3 0/5] sunrpc: add some debugfs files for dumping task and xprt info

[Jeff Layton <jlayton@primarydata.com>]

v3:
- add a patch that creates and populates a rpc_xprt directory
- take reference on rpc_clnt when "tasks" file is opened
- minor cleanups

v2:
- add a whole new directory hierarchy instead of a single
  client_tasks file
- respin patches to remove LOCKD_DEBUG/RPC_DEBUG/RPC_TRACEPOINTS defines

Ok, here is the latest (and hopefully last!) respin of the patches to
add some debugfs files to dump info about rpc_clnt and rpc_xprt
objects.

This set ensures that references are properly acquired so that the
objects don't disappear while we're working on them. I've also included
the patches to eliminate the RPC_DEBUG defines too as they should be
merged first to prevent conflicts.

Trond, can you consider these for v3.19?

Thanks!
