Subject: nfs: Fix fscache stat printing in nfs_show_stats()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ce85bd29210f2cd84dc1f762c3992d8e6db822c2;p=linux.git

nfs: Fix fscache stat printing in nfs_show_stats()

nfs_show_stats() was incorrectly reading statistics for bytes when printing that
for fsc. It caused files like /proc/self/mountstats to report incorrect fsc
statistics for NFS mounts.
