[GIT PULL] libnvdimm for 4.5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus, please pull from...

+AKA- git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-4.5

...to receive the libnvdimm update for 4.5.

The bulk of this has appeared in -next and independently received a
+AKA-build success notification from the kbuild robot. +AKA-The 'for-4.5/block-
dax' topic branch was rebased over the weekend to drop the +ACI-block
device end-of-life+ACI- rework that Al would like to see re-implemented
with a notifier, and to address bug reports against the badblocks
integration.

There is pending feedback against +ACI-libnvdimm: Add a poison list and
export badblocks+ACI- received last week. +AKA-Linda identified some localized
fixups that we will handle incrementally.

This update has a minor conflict with the dax updates pending in -mm,
but only for both sides wanting to add a new header-file-include to
drivers/nvdimm/pmem.c.

+AKA- Merge branch 'for-4.5/block-dax' into for-4.5/libnvdimm (2016-01-10 07:53:55 -0800)

----------------------------------------------------------------
libnvdimm for 4.5

1/ Media error handling: The 'badblocks' implementation that originated
+AKAAoACg-in md-raid is up-levelled to a generic capability of a block device.
+AKAAoACg-This initial implementation is limited to being consulted in the pmem
+AKAAoACg-block-i/o path.+AKAAoA-Later, 'badblocks' will be consulted when creating
+AKAAoACg-dax mappings.

2/ Raw block device dax: For virtualization and other cases that want
+AKAAoACg-large contiguous mappings of persistent memory, add the capability to
+AKAAoACg-dax-mmap a block device directly.

3/ Increased /dev/mem restrictions: Add an option to treat all io-memory
+AKAAoACg-as IORESOURCE+AF8-EXCLUSIVE, i.e. disable /dev/mem access while a driver is
+AKAAoACg-actively using an address range.+AKAAoA-This behavior is controlled via the
+AKAAoACg-new CONFIG+AF8-IO+AF8-STRICT+AF8-DEVMEM option and can be overridden by the
+AKAAoACg-existing +ACI-iomem+AD0-relaxed+ACI- kernel command line option.

4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
+AKAAoACg-block device shutdown crash fix, and other small libnvdimm fixes.
