Subject: nilfs2: convert recovery logic to use kmap_local
Date: Mon, 22 Jan 2024 23:01:48 +0900

Patch series "nilfs2: eliminate kmap and kmap_atomic calls".

This series converts remaining kmap and kmap_atomic calls to use
kmap_local, mainly in metadata files, and eliminates calls to these
deprecated kmap functions from nilfs2.

This series does not include converting metadata files to use folios, but
it is a step in that direction.

Most conversions are straightforward, but some are not: the checkpoint
file, the inode file, and the persistent object allocator.  These have
been adjusted or rewritten to avoid multiple kmap_local calls or nest them
if necessary, and to eliminate long waits like block I/O within the
highmem mapping sections.

This series has been tested in both 32-bit and 64-bit environments with
varying block sizes.


This patch (of 15):

In the recovery function when mounting, nilfs_recovery_copy_block() uses
the deprecated kmap_atomic(), so convert it to use kmap_local.
