Subject: [ndctl PATCH v2 00/10] fixes and movability for system-ram mode
Date: Sat, 19 Oct 2019 21:23:22 -0600	[thread overview]
Message-ID: <20191020032332.16776-1-vishal.l.verma@intel.com> (raw)

v2:
- Change MEM_FIND_ZONE to MEM_GET_ZONE (Dan)
- Remove the verbose race warning from runtime and just point to the man
  page (Dan)
- Remove the short option for '--no-movable' (Dan)

This patchset improves the user experience around memory onlining,
specifically the state it is onlined in - movable vs non-movable. It
also adds an option to make the memory non-movable when onlining.

Patches 1-3 perform some preparatory and clean up steps.
Patches 4-6 add a way to determine and display the 'movable' vs
'non-movable' state of memory.
Patches 7-8 attempt to detect a race with memory onlining, and add a
Documentation clarification
Patches 9-10 Add the new --no-movable option to commands that may
online memory.

Vishal Verma (10):
  libdaxctl: refactor path construction in op_for_one_memblock()
  libdaxctl: refactor memblock_is_online() checks
  daxctl/device.c: fix json output omission for reconfigure-device
  libdaxctl: add an API to determine if memory is movable
  libdaxctl: allow memblock_in_dev() to return an error
  daxctl: show a 'movable' attribute in device listings
  daxctl: detect races when onlining memory blocks
  Documentation: clarify memory movablity for reconfigure-device
  libdaxctl: add an API to online memory in a non-movable state
  daxctl: add --no-movable option for onlining memory
