[PATCH v3 0/6] gfs2: kmap{_atomic} conversion to kmap_local_{page/folio}

[Deepak R Varma]

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

  gfs2: Replace kmap_atomic() by kmap_local_page() in stuffed_readpage
  gfs2: Replace kmap_atomic()+memcpy by memcpy_from_page()
  gfs2: Replace kmap() by kmap_local_page() in gfs2_unstuffer_page
  gfs2: Replace kmap_atomic() by kmap_local_page() in lops.c
  gfs2: Replace kmap() by kmap_local_page() in gfs2_read_super
  gfs2: Replace kmap_atomic() by kmap_local_page() in
    gfs2_write_buf_to_page
