Message-ID: <20250513053809.699974-2-ebiggers@kernel.org>
Date: Mon, 12 May 2025 22:38:06 -0700
From: Eric Biggers <ebiggers@...nel.org>
To: linux-ext4@...r.kernel.org
Subject: [PATCH 1/4] ext4: remove sbi argument from ext4_chksum()
From: Eric Biggers <ebiggers@...gle.com>
Since ext4_chksum() no longer uses its sbi argument, remove it.
