afs: Add stats for data transfer operations
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. Signed-off-by: David Howells <dhowells@redhat.com>
