[PATCH 0/3] 1G transparent hugepage support for device dax
by Dave Jiang
The following series implements support for 1G trasparent hugepage on
x86 for device dax. The bulk of the code was written by Mathew Wilcox
a while back supporting transparent 1G hugepage for fs DAX. I have
forward ported the relevant bits to 4.10-rc. The current submission has
only the necessary code to support device DAX.

RE: [LSF/MM TOPIC] Badblocks checking/representation in filesystems

As I remember, FAT and HFS+ specifications contain description of bad blocks
(physical sectors) table. I believe that this table was used for the case of
floppy media. But, finally, this table becomes to be the completely obsolete
artefact because mostly storage devices are reliably enough. Why do you need
in exposing the bad blocks on the file system level? Do you expect that next
generation of NVM memory will be so unreliable that file system needs to manage
bad blocks? What's about erasure coding schemes? Do file system really need to suffer
from the bad block issue?
Usually, we are using LBAs and it is the responsibility of storage device to map
a bad physical block/page/sector into valid one. Do you mean that we have
access to physical NVM memory address directly? But it looks like that we can
have a "bad block" issue even we will access data into page cache's memory
page (if we will use NVM memory for page cache, of course). So, what do you
imply by "bad block" issue?

What do you mean by "file system can check the IO happening on a file"?
Do you mean read or write operation? What's about metadata?
If we are talking about the discovering a bad block on read operation then
rare modern file system is able to survive as for the case of metadata as
for the case of user data. Let's imagine that we have really mature file
system driver then what does it mean to encounter a bad block? The failure
to read a logical block of some metadata (bad block) means that we are
unable to extract some part of a metadata structure. From file system
driver point of view, it looks like that our file system is corrupted, we need
to stop the file system operations and, finally, to check and recover file
system volume by means of fsck tool. If we find a bad block for some
user file then, again, it looks like an issue. Some file systems simply
return "unrecovered read error". Another one, theoretically, is able
to survive because of snapshots, for example. But, anyway, it will look
like as Read-Only mount state and the user will need to resolve such
trouble by hands.
If we are talking about discovering a bad block during write operation then,
again, we are in trouble. Usually, we are using asynchronous model
of write/flush operation. We are preparing the consistent state of all our
metadata structures in the memory, at first. The flush operations for metadata
and user data can be done in different times. And what should be done if we
discover bad block for any piece of metadata or user data? Simple tracking of
bad blocks is not enough at all. Let's consider user data, at first. If we cannot
write some file's block successfully then we have two ways: (1) forget about
this piece of data; (2) try to change the associated LBA for this piece of data.
The operation of re-allocation LBA number for discovered bad block
(user data case) sounds as real pain. Because you need to rebuild the metadata
that track the location of this part of file. And it sounds as practically
impossible operation, for the case of LFS file system, for example.
If we have trouble with flushing any part of metadata then it sounds as
complete disaster for any file system.
Are you really sure that file system should process bad block issue?

I am not sure that any bad block notification during/after IO operation
is valuable for file system. Maybe, it could help if file system simply will
know about bad block beforehand the operation of logical block allocation.
But what subsystem will discover bad blocks before any IO operations?
How file system will receive information or some bad block table?
I am not convinced that suggested badblocks approach is really feasible.
Also I am not sure that file system should see the bad blocks at all.
Why hardware cannot manage this issue for us?

[ndctl PATCH v2] ndctl, create-namespace: add an 'align' option
by Dan Williams
When memory-mode support was added to the kernel it also included a
facility to set the alignment of the namespace. By default it is set to
2M, but 4K and 1G are also valid options. Add this support to the
utility. As Dave notes, this is prompted by the desire to add test
support for device-dax using nfit-test resources. Given the nfit_test
resources are backed by vmalloc, the only alignment nfit_test can
support is 4K.
Based on an earlier patch by Dave Jiang.

Changes in v2:
* fix default alignment handling, catch the default case and don't
enforce alignment checks for older kernels or modes where it doesn't
make sense.
* fix up / clarify code comments

[PATCH] mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf
by Dave Jiang
->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take
a vma and vmf parameter when the vma already resides in vmf. Remove the vma
parameter to simplify things.
Signed-off-by: Dave Jiang <dave.jiang(a)intel.com>

[GIT PULL] libnvdimm fixes for 4.10-rc5
by Dan Williams
Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm libnvdimm-fixes
...to receive:
* A regression fix for the multiple-pmem-namespace-per-region support
added in 4.9. Even if an existing environment is not using that
feature the act of creating and a destroying a single namespace with
the ndctl utility will lead to the proliferation of extra unwanted
namespace devices.
* A fix for the error code returned from the pmem driver when the
memcpy_mcsafe() routine returns -EFAULT. Btrfs seems to be the only
block I/O consumer that tries to parse the meaning of the error code
when it is non-zero.
Neither of these fixes are critical, the namespace leak is awkward in
that it can cause device naming to change and complicates debugging
namespace initialization issues. The error code fix is included out of
caution for what other consumers might be expecting -EIO for block I/O
errors.

pmem: return EIO on read_pmem() failure
The read_pmem() function uses memcpy_mcsafe() on x86 where an EFAULT
error code indicates a failed read. Block I/O should use EIO to
indicate failure. Other pmem code paths (like bad blocks) already use
EIO so let's be consistent.
This fixes compatibility with consumers like btrfs that try to parse the
specific error code rather than treat all errors the same.

libnvdimm, namespace: fix pmem namespace leak, delete when size set to zero
Commit 98a29c39dc68 ("libnvdimm, namespace: allow creation of multiple
pmem-namespaces per region") added support for establishing additional
pmem namespace beyond the seed device, similar to blk namespaces.
However, it neglected to delete the namespace when the size is set to
zero.
