Subject: nfs: Fix fscache stat printing in nfs_show_stats()
X-Git-Tag: v4.13-rc1~30^2~26

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.
