Subject: [PATCH 0/5] device-dax and huge-page dax fixes for 4.8-rc6
Date: Tue, 06 Sep 2016 09:49:20 -0700 [thread overview]
Message-ID: <147318056046.30325.5100892122988191500.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
Kai and Toshi reported poor performance with huge-page dax mappings and
while debugging a few more bugs were discovered in the device-dax driver
and mm. The following fixes target 4.8-rc6 and are tagged for -stable:
- device-dax incorrectly translates the file offset to a physical
resource address
- show_smap() crashes on huge-page dax mappings
- huge-page dax mappings are inadvertently being marked as
_PAGE_CACHE_MODE_UC instead of _PAGE_CACHE_MODE_WB
I would like to take this set through nvdimm.git with acks from mm folks
as there is 4.9 device-dax development that depends on these changes.
