[PATCH daxctl v2 0/5] daxctl: device align support

[Joao Martins <joao.m.martins@oracle.com>]

Hey,

This series adds support for:

 1) {create,reconfigure}-device for selecting @align (hugepage size).
 Here we add a '-a|--align 4K|2M|1G' option to the existing commands;

 2) Listing now displays align (if supported).

Testing requires a 5.10+ kernel. 

v1 -> v2:
  * Fix listing of dax devices on kernels that don't support align;
  * Adds a unit test for align;
  * Remove the mapping part to a later series;

Joao Martins (5):
  daxctl: add daxctl_dev_{get,set}_align()
  util/json: Print device align
  daxctl: add align support in reconfigure-device
  daxctl: add align support in create-device
  daxctl/test: Add a test for daxctl-create with align
