Subject: RFC: buffer cache backing page allocation cleanup
Date: Wed, 19 May 2021 21:08:49 +0200	[thread overview]
Message-ID: <20210519190900.320044-1-hch@lst.de> (raw)

Hi all,

while reviewing the patch from Dave to use alloc_pages_bulk_array I
stumbled over all kinds of lose end in the buffer cache, and I started
cleaning them up while procrastinating and avoiding more urgent work,
and rebased the alloc_pages_bulk_array patch on top.

Only run through a quick group xfstests run on a 4k file system so far.
