Subject: [PATCH 0/2] Pool for compression pages
Date: Wed, 15 Nov 2023 17:59:37 +0100 [thread overview]
Message-ID: <cover.1700067287.git.dsterba@suse.com> (raw)
Add wrappers for alloc/free of pages used for compresion and keep a
small cache (for all filesystems, ie. per module). This can speed up
short compression IO when we don't need to go to the allocator. Shrinker
is attached to free the pages if there's memory pressure.

btrfs: use page alloc/free wrapeprs for compression pages
