From: Eric Biggers <ebiggers@google.com> stable inclusion from stable-v5.10.121 commit d54ac6ca48c1fa44868faffcba7d8aeab8937f2e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6CQ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit cb8435dc8ba33bcafa41cf2aa253794320a3b8df ] The 'commit' option is only applicable for ext3 and ext4 filesystems, and has never been accepted by the ext2 filesystem driver, so the ext4 driver shouldn't allow it on ext2 filesystems. This fixes a failure in xfstest ext4/053. Fixes: 8dc0aa8cf0f7 ("ext4: check incompatible mount options while mounting ext2/3") Signed-off-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Ritesh Harjani <ritesh.list@gmail.com> Reviewed-by: Lukas Czerner <lczerner@redhat.com> Link: https://lore.kernel.org/r/20220510183232.172615-1-ebiggers@kernel.org Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Zheng Zengkai <zhengzengkai@huawei.com> Acked-by: Xie XiuQi <xiexiuqi@huawei.com> --- fs/ext4/super.c | 1 + 1 file changed, 1 insertion(+) diff --git a/fs/ext4/super.c b/fs/ext4/super.c index 706a159817ee..cf988c4068b0 100644 --- a/fs/ext4/super.c +++ b/fs/ext4/super.c @@ -1981,6 +1981,7 @@ static const struct mount_opts { MOPT_EXT4_ONLY | MOPT_CLEAR}, {Opt_warn_on_error, EXT4_MOUNT_WARN_ON_ERROR, MOPT_SET}, {Opt_nowarn_on_error, EXT4_MOUNT_WARN_ON_ERROR, MOPT_CLEAR}, + {Opt_commit, 0, MOPT_NO_EXT2}, {Opt_nojournal_checksum, EXT4_MOUNT_JOURNAL_CHECKSUM, MOPT_EXT4_ONLY | MOPT_CLEAR}, {Opt_journal_checksum, EXT4_MOUNT_JOURNAL_CHECKSUM, -- 2.20.1
