Subject: [PATCH v13 72/72] radix tree: Remove radix_tree_clear_tags
Date: Mon, 11 Jun 2018 07:06:39 -0700 [thread overview]
Message-ID: <20180611140639.17215-73-willy@infradead.org> (raw)
In-Reply-To: <20180611140639.17215-1-willy@infradead.org>
From: Matthew Wilcox <mawilcox@microsoft.com>
The page cache was the only user of this interface and it has now
been converted to the XArray. Transform the test into a test of
xas_init_tags().
