This patch series proposes to replace the kmap/kmap_atomic implementation to the
preferred kmap_local_* APIs.
The code blocks for this module where kmap/kmap_atomic calls are implemented do
not appear to depend on disabling page-faults or preemption. Hence such code
blocks are safe for converting to improved kmap_local_{page,folio} APIs.
Note: The proposed patches are build tested only.
Initially, only a single patch was sent and now being converted into a patch
series including the other files/functions of this module. Hence all patches,
that are included for the first time in this series are also marked as v3.
Changes in v3:
- Patch set introduced to include all gfs2 kmap conversions
- Patches 3/6 through 6/6 are included to build the series
- Initial stand-alone patch split into 2 patches [1/6 and 2/6]
Changes in v2:
- 3/6 to 6/6: None.
- 1/6 + 2/6: Correct patch description for the replacement function name from
kmap_local_folio to kmap_local_page
