Subject: buffer: Remove check for PageError
X-Git-Tag: folio-6.0~41
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=6e8e79fc84435c159891182cddab8e7784e1b3b2;p=users%2Fwilly%2Fpagecache.git

buffer: Remove check for PageError

If a buffer is completed with an error, its uptodate flag will be clear,
so the page_uptodate variable will have been set to 0.  There's no
need to check PageError here.
