Subject: [PATCH v4 02/12] readahead: Ignore return value of ->readpages
Date: Sat, 1 Feb 2020 07:12:30 -0800 [thread overview]
Message-ID: <20200201151240.24082-3-willy@infradead.org> (raw)
In-Reply-To: <20200201151240.24082-1-willy@infradead.org>
From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
We used to assign the return value to a variable, which we then ignored.
Remove the pretence of caring.
