Subject: remove Xen tmem leftovers
Date: Fri, 24 Dec 2021 07:22:33 +0100 [thread overview]
Message-ID: <20211224062246.1258487-1-hch@lst.de> (raw)
Hi all,
since the remove of the Xen tmem driver in 2019, the cleancache hooks are
entirely unused, as are large parts of frontswap. This series against
linux-next (with the folio changes included) removes cleancaches, and cuts
down frontswap to the bits actually used by zswap.
