Subject: btrfs compressed writeback cleanups
Date: Wed, 28 Jun 2023 17:31:21 +0200	[thread overview]
Message-ID: <20230628153144.22834-1-hch@lst.de> (raw)

Hi all,

this series is a prequel to another big set of writeback patches, and
mostly deals with compressed writeback, which does a few things very
different from other writeback code.  The biggest results are the removal
of the magic redirtying when handing off to the worker thread, and a fix
for out of zone active resources handling when using compressed writeback
on a zoned file system, but mostly it just removes a whole bunch of code.

Note that the first 5 patches have been out on the btrfs list as
standalone submissions for a while, but they are included for completeness
so that this series can be easily applied to the btrfs misc-next tree.
