From 76a5cb6fc1e22a2a316fb690fc4cdd5121d1c0ff Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 6 Apr 2018 14:17:26 +0100 Subject: 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.
