Subject: [PATCH 7/8] mm: Use xas_erase() in collapse_file()
Date: Tue, 4 Feb 2020 15:25:13 +0100 [thread overview]
Message-ID: <20200204142514.15826-8-jack@suse.cz> (raw)
In-Reply-To: <20200204142514.15826-1-jack@suse.cz>
When undoing failed collapse of ordinary pages into a huge page, use
xas_erase() to explicitly clear any xarray marks that may have been
added to entries.
