Subject: [PATCH 03/15] nilfs2: convert nilfs_copy_buffer() to use kmap_local
Date: Mon, 22 Jan 2024 23:01:50 +0900	[thread overview]
Message-ID: <20240122140202.6950-4-konishi.ryusuke@gmail.com> (raw)
In-Reply-To: <20240122140202.6950-1-konishi.ryusuke@gmail.com>

The routine nilfs_copy_buffer() that copies a block buffer still uses
the deprecated kmap_atomic(), so convert it to use kmap_local.
