Subject: [PATCH 00/14] fscache: Rewrite 1: Disable and clean in preparation for rewrite
Date: Mon, 13 Jul 2020 17:27:43 +0100 [thread overview]
Message-ID: <159465766378.1376105.11619976251039287525.stgit@warthog.procyon.org.uk> (raw)
Here's a set of patches that disables the network filesystems that use
fscache and then remove a whole chunk of the fscache codebase pending it
being rewritten.
The following parts of fscache have been removed:
- The object state machine
- The I/O operation manager
- All non-transient references from fscache to the netfs's data
- All non-transient callbacks from fscache to the netfs
- The backing page I/O monitoring
- The tracking of netfs pages that fscache knows about
- The tracking of netfs pages that need writing to the cache
- The use of bmap to work out if a page is stored in the cache
- The copy of data to/from backing pages to netfs pages.
The corresponding cachefiles bits have also been removed.
These patches can be found as part of the branch here:
