[PATCH 0/8] Write-intent bitmap support for IMSM metadata

This patchset is aimed to add write-intent bitmap support for IMSM
metadata.

Additional function in the superswitch (set_bitmap) is proposed as
a place where the internal bitmaps configuration for non-native
metadata can be performed (through sysfs).

Adding the bitmap to existing volumes is implemented similarly like
for the PPL functionality (through --update-subarray).

The patchset was tested on HW and qemu.

Jakub Radtke (8):
  Modify mdstat parsing for volumes with the bitmap
  Enable bitmap support for external metadata
  imsm: Write-intent bitmap support
  imsm: Adding a spare to an existing array with bitmap
  Add "bitmap" to allowed command-line values
  imsm: Update-subarray for write-intent bitmap
  Create: Block automatic enabling bitmap for external metadata
  Grow: Block reshape when external metadata and write-intent bitmap
