Subject: [PATCH 01/15] nilfs2: convert recovery logic to use kmap_local
Date: Mon, 22 Jan 2024 23:01:48 +0900 [thread overview]
Message-ID: <20240122140202.6950-2-konishi.ryusuke@gmail.com> (raw)
In-Reply-To: <20240122140202.6950-1-konishi.ryusuke@gmail.com>
In the recovery function when mounting, nilfs_recovery_copy_block() uses
the deprecated kmap_atomic(), so convert it to use kmap_local.
