fscache, cachefiles: Remove the histogram stuff
Remove the histogram stuff as it's mostly going to be outdated. Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> cc: linux-cachefs@redhat.com Link: https://lore.kernel.org/r/162431195953.2908479.16770977195634296638.stgit@warthog.procyon.org.uk/

-config FSCACHE_HISTOGRAM
- bool "Gather latency information on local caching"
- depends on FSCACHE && PROC_FS
- help
- This option causes latency information to be gathered on local
- caching and exported through file:
-
- /proc/fs/fscache/histogram
-
- The generation of this histogram adds a certain amount of overhead to
- execution as there are a number of points at which data is gathered,
- and on a multi-CPU system these may be on cachelines that keep
- bouncing between CPUs. On the other hand, the histogram may be
- useful for debugging purposes. Saying 'N' here is recommended.
