Subject: [PATCH 05/16] fuse2fs: use tagged block IO for zeroing sub-block
 regions

From: Darrick J. Wong <djwong@...nel.org>

Change the punch hole helpers to use the tagged block IO commands now
that libext2fs uses tagged block IO commands for file IO.  We'll need
this in the next patch when we turn on selective IO manager cache
clearing and invalidation.
