Subject: [PATCH 09/13] hostfs: Tell the VFS that readpage was synchronous
Date: Thu, 17 Sep 2020 16:10:46 +0100 [thread overview]
Message-ID: <20200917151050.5363-10-willy@infradead.org> (raw)
In-Reply-To: <20200917151050.5363-1-willy@infradead.org>
The hostfs readpage implementation was already synchronous, so use
AOP_UPDATED_PAGE to avoid cycling the page lock.
Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
