Subject: [PATCH 0/6] dax: Page invalidation fixes
Date: Tue, 27 Sep 2016 18:43:29 +0200 [thread overview]
Message-ID: <1474994615-29553-1-git-send-email-jack@suse.cz> (raw)
Hello,
these patches fix races when invalidating hole pages in DAX mappings. See
changelogs for details. The series is based on my patches to write-protect
DAX PTEs because we really need to closely track dirtiness (and cleanness!)
of radix tree entries in DAX mappings in order to avoid discarding valid
dirty bits leading to missed cache flushes on fsync(2).
