Subject: [PATCH v3 0/2] Add DAX ABI for memmap_on_memory
Date: Mon, 11 Dec 2023 15:52:16 -0700 [thread overview]
Message-ID: <20231211-vv-dax_abi-v3-0-acf6cc1bde9f@intel.com> (raw)
The DAX drivers were missing sysfs ABI documentation entirely. Add this
missing documentation for the sysfs ABI for DAX regions and Dax devices
in patch 1. Add a new ABI for toggling memmap_on_memory semantics in
patch 2.
The missing ABI was spotted in [1], this series is a split of the new
ABI additions behind the initial documentation creation.

Changes in v3:
- Fix typo in ABI docs (Zhijian Li)
- Add kernel config and module parameter dependencies to the ABI docs
entry (David Hildenbrand)
- Ensure kmem isn't active when setting the sysfs attribute (Ying
Huang)
- Simplify returning from memmap_on_memory_store()
- Link to v2: https://lore.kernel.org/r/20231206-vv-dax_abi-v2-0-f4f4f2336d08@intel.com
Changes in v2:
- Fix CC lists, patch 1/2 didn't get sent correctly in v1
- Link to v1: https://lore.kernel.org/r/20231206-vv-dax_abi-v1-0-474eb88e201c@intel.com
