From e64855c6cfaa0a80c1b71c5f647cb792dc436668 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Fri, 4 Nov 2016 18:08:15 +0100 Subject: fs: Add helper to clean bdev aliases under a bh and use it Add a helper function that clears buffer heads from a block device aliasing passed bh. Use this helper function from filesystems instead of the original unmap_underlying_metadata() to save some boiler plate code and also have a better name for the functionalily since it is not unmapping anything for a *long* time.
