Subject: [PATCH] bcache: Move couple of string arrays to sysfs.c
Git-commit: 04cbc21137bfa4d7b8771a5b14f3d6c9b2aee671
Patch-mainline: v4.18-rc1
References: bsc#1111974,bsc#1130972

There is couple of string arrays that are used exclusively in sysfs.c.
Move it to there and make them static.

Besides above, it will allow further clean up.

No functional change intended.
