[PATCH] dm-verity: skip verity_handle_err on I/O errors for metadata
From: Akilesh Kailash
Date: Sat Feb 08 2025 - 18:19:44 EST
Handle I/O error for metadata blocks if FEC correction fails.
This is similar to handling I/O error for data blocks:
'commit 2c0468e054c0 ("dm verity: skip redundant verity_handle_err()
on I/O errors")'
Fixes: 2c0468e054c0 ("dm verity: skip redundant verity_handle_err()
on I/O errors")
Signed-off-by: Akilesh Kailash <akailash@xxxxxxxxxx>

Note: This patch should have been included in the data block fix patch.
A "fixes" tag has been added to address this.
