Subject: [PATCH 0/4] fs: Provide function to unmap metadata for a range of blocks
Date: Fri, 21 Oct 2016 13:55:37 +0200 [thread overview]
Message-ID: <1477050941-29682-1-git-send-email-jack@suse.cz> (raw)
Hello,
I've noticed that in several places we need to unmap metadata in buffer cache
for a range of blocks and we do it by iterating over all blocks in given
range. Let's provide a helper function for that and implement it in a way
more efficient for larger ranges or blocks. The patches passed xfstests
for ext2 and ext4.
Jens, can you merge these patches if they look fine to you?
Honza
