From 0631d5e02a1c722b90c11a47dcb6d83ef88ab47b Mon Sep 17 00:00:00 2001 From: Dave Wysochanski Date: Mon, 20 Feb 2023 08:43:07 -0500 Subject: NFS: Remove all NFSIOS_FSCACHE counters due to conversion to netfs API The old NFSIOS_FSCACHE counters are no longer accurate or useful with the conversion to the new netfs API. The new API does not have a page based interface, and so the counters in nfs_stat_fscachecounters are no longer obtainable. The new netfs the API has extensive statistics inside /proc/fs/fscache/stats so we no longer need NFS specific fscache stats. Note this also removes the 'fsc:' line from /proc/self/mountstats so it will be a user-visible change.
