Subject: RFC: optimize COW end I/O remapping
Date: Thu, 28 Mar 2024 08:02:50 +0100	[thread overview]
Message-ID: <20240328070256.2918605-1-hch@lst.de> (raw)

Hi all,

this series optimizes how we handle unmapping the old data fork
extents when finishing COW I/O.  To get there I also did a bunch
of cleanups for helpers called by this code.

Note that this conflicts with both Darrick's repair work and my
RT delalloc series, so it will need a rebase after those are merged.
