Show all of a server's addresses in /proc/fs/afs/servers, placing the

afs: Implement network namespacing

2018-05-23T11:01:15+00:00

Implement network namespacing within AFS, but don't yet let mounts occur
outside the init namespace.  An additional patch will be required propagate
the network namespace across automounts.

afs: Mark afs_net::ws_cell as __rcu and set using rcu functions

2018-05-23T10:51:29+00:00

The afs_net::ws_cell member is sometimes used under RCU conditions from
within an seq-readlock.  It isn't, however, marked __rcu and it isn't set
using the proper RCU barrier-imposing functions.

Fix this by annotating it with __rcu and using appropriate barriers to
make sure accesses are correctly ordered.

Without this, the code can produce the following warning:

>> fs/afs/proc.c:151:24: sparse: incompatible types in comparison expression (different address spaces)

afs: Rearrange fs/afs/proc.c to move the show routines up

2018-05-18T10:46:14+00:00

Rearrange fs/afs/proc.c to move the show routines up to the top of each
block so the order is show, iteration, ops, file ops, fops.

afs: Move /proc management functions to the end of the file

2018-05-18T10:46:14+00:00

end of the source file as a first stage in getting rid of all the forward
declarations.

afs: simplify procfs code

2018-05-16T05:24:30+00:00

Use remove_proc_subtree to remove the whole subtree on cleanup, and
unwind the registration loop into individual calls.  Switch to use
proc_create_seq where applicable.

afs: Add stats for data transfer operations

2018-04-09T20:54:48+00:00

Add statistics to /proc/fs/afs/stats for data transfer RPC operations.  New
lines are added that look like:

	file-rd : n=55794 nb=10252282150
	file-wr : n=9789 nb=3247763645

where n= indicates the number of ops completed and nb= indicates the number
of bytes successfully transferred.  file-rd is the counts for read/fetch
operations and file-wr the counts for write/store operations.

Note that directory and symlink downloading are included in the file-rd
stats at the moment.

afs: Locally edit directory data for mkdir/create/unlink/...

2018-04-09T20:54:48+00:00

Locally edit the contents of an AFS directory upon a successful inode
operation that modifies that directory (such as mkdir, create and unlink)
so that we can avoid the current practice of re-downloading the directory
after each change.

This is viable provided that the directory version number we get back from
the modifying RPC op is exactly incremented by 1 from what we had
previously.  The data in the directory contents is in a defined format that
we have to parse locally to perform lookups and readdir, so modifying isn't
a problem.

If the edit fails, we just clear the VALID flag on the directory and it
will be reloaded next time it is needed.
