Subject: [PATCH 1/14] mm: invalidate_mapping_pages flush cleancache
Date: Mon, 30 May 2011 17:35:46 -0700 (PDT) [thread overview]
Message-ID: <alpine.LSU.2.00.1105301733500.5482@sister.anvils> (raw)
In-Reply-To: <alpine.LSU.2.00.1105301726180.5482@sister.anvils>
truncate_inode_pages_range() and invalidate_inode_pages2_range()
call cleancache_flush_inode(mapping) before and after: shouldn't
invalidate_mapping_pages() be doing the same?
