[ndctl PATCH v3 0/8] Improvements for namespace creation/interrogation
by Dan Williams
Changes since v2 [1]:
- Drop the patches that have already been applied to the 'pending' branch
- Rebase the dimm extent series and the small 'create-namespace' fixlets
- Move the new libndctl apis to the next library symbol version (Vishal)
- Defer the following to a post ndctl-v66 release:
ndctl/namespace: Add read-infoblock command
ndctl/test: Update dax-dev to handle multiple e820 ranges
ndctl/test: Make dax.sh more robust vs small namespaces
ndctl/namespace: Always zero info-blocks
ndctl/namespace: Disable autorecovery of create-namespace failures
ndctl/test: Checkout device-mapper + dax operation
ndctl/test: Exercise sub-section sized namespace creation/deletion
ndctl/namespace: Kill off the legacy mode names
ndctl/namespace: Introduce mode-to-name and name-to-mode helpers
ndctl/namespace: Validate namespace size within validate_namespace_options()
ndctl/namespace: Clarify 16M minimum size requirement

This trimmed version includes the extent support for label operations
which significantly speeds up common label operations like
'init-labels'. It also fixes up some surprising results from
'create-namespace' where it would fail even though available capacity is
present. Lastly it suppresses a new warning found in Fedora Rawhide
builds that has moved to gcc 9.1.1.

Dan Williams (8):
ndctl/build: Suppress -Waddress-of-packed-member
ndctl/dimm: Support small label reads/writes
ndctl/dimm: Minimize data-transfer for init-labels
ndctl/dimm: Add offset and size options to {read,write,zero}-labels
ndctl/dimm: Limit read-labels with --index option
ndctl/namespace: Minimize label data transfer for autolabel
ndctl/namespace: Continue region search on 'missing seed' event
ndctl/namespace: Report ENOSPC when regions are full

[PATCH] memremap: move from kernel/ to mm/
by Christoph Hellwig
memremap.c implements MM functionality for ZONE_DEVICE, so it really
should be in the mm/ directory, not the kernel/ one.

[PATCH] daxctl: link against libndctl, in case its use doesn't get pruned
by Adam Borowski
util/json.c uses libndctl symbols, and is included by daxctl. These
functions should then get pruned as unused, but on some platforms the
toolchain fails to do so.
These platforms are ia64, hppa and 32-bit powerpc. It's generally a
waste of our time to build ndctl there, but as the lack of a
build-dependency requires annoying workarounds higher in the stack,
this has been requested in https://bugs.debian.org/914348 -- and is
trivially fixable on the ndctl side.
Thanks to -Wl,--as-needed there's no harm to architectures where the
pruning works, thus let's not bother with detection.
As daxctl and libdaxctl are separate, there's no circular dependency.

[ndctl PATCH] ndctl/monitor: make the daemon exit message 'info' level
by Vishal Verma
The 'ndctl monitor daemon started' message is at an 'info' log level,
but the corresponding exit message (if no DIMMs are found for
monitoring) was only at a 'debug' level. As a result, on a system
without NVDIMMs, the sysadmin might see a 'monitor started' message, but
a monitor wouldn't actually be running. Making the exit message the same
log level ensures that no confusion arises out of this.
