Subject: Re: [PATCH 26/27] ext4: add KUnit tests for fs/ext4/mmp.c
Date: Thu, 12 Nov 2026 04:29:59 +0000 [thread overview]
Message-ID: <sashiko-outbox-210341@kernel.org> (raw)
In-Reply-To: <20261112040638.1576836-27-tytso@mit.edu>
> Add a KUnit test suite (ext4_mmp_test) covering multi-mount protection
> checksums, block I/O validation, and mount state transitions in
> fs/ext4/mmp.c:
>
> - CRC32C generation and verification in ext4_mmp_csum_set() and
> ext4_mmp_csum_verify() with and without METADATA_CSUM
> - Block read/write error handling, magic validation (-EFSCORRUPTED),
> CRC mismatch handling (-EFSBADCRC), and buffer cleanup in
> read_mmp_block() and write_mmp_block()
> - ext4_multi_mount_protect() validation of out-of-range MMP blocks,
> EXT4_MMP_SEQ_FSCK rejection (-EBUSY), EXT4_MMP_SEQ_CLEAN claim and
> ext4_stop_mmpd() teardown, active/racing node sequence conflicts,
> check_interval clamping, interrupted waits (-ETIMEDOUT), and kthread
> startup failure
>
