Hi,

I've just built and booted 4.3.0-rc2 and I'm seeing the following new messages on the console during boot up:

[    2.481399] EXT4-fs (sda2): couldn't mount as ext3 due to feature incompatibilities
[    2.482426] EXT4-fs (sda2): couldn't mount as ext2 due to feature incompatibilities

They are immediately followed by:

[    2.507948] EXT4-fs (sda2): mounted filesystem with ordered data mode. Opts: (null)
[    3.549523] EXT4-fs (sda2): re-mounted. Opts: (null)

and they are the messages I normally see (from 4.2.0 and earlier).

sda2 is my root partition and is mounted OK, so my system is operating as before, but I thought you would want a heads
up about these (slightly alarming) new console messages.

The output from dmesg is attached, in case it helps.

Chris

Applying the 4.2.1-rc1 patch results in a kernel that emits the messages, so I guess my fix-not-yet-in-4.2 theory is right.

I'll just ignore the messages. Sorry for the noise.

Thanks Ortwin.

No, I do not get the messages from 4.2.0 even though it is configured the same as 4.3.0-rc3 as far as EXT{2,3,4} is
concerned:

# CONFIG_EXT2_FS is not set
# CONFIG_EXT3_FS is not set
CONFIG_EXT4_FS=y
CONFIG_EXT4_USE_FOR_EXT2=y
# CONFIG_EXT4_FS_POSIX_ACL is not set
# CONFIG_EXT4_FS_SECURITY is not set
# CONFIG_EXT4_ENCRYPTION is not set
# CONFIG_EXT4_DEBUG is not set
[chris:~/kernel/linux]$ cd ../linux-4.2.0/
[chris:~/kernel/linux-4.2.0]$ grep EXT[234] .config
# CONFIG_EXT2_FS is not set
# CONFIG_EXT3_FS is not set
CONFIG_EXT4_FS=y
CONFIG_EXT4_USE_FOR_EXT23=y
# CONFIG_EXT4_FS_POSIX_ACL is not set
# CONFIG_EXT4_FS_SECURITY is not set
# CONFIG_EXT4_ENCRYPTION is not set
# CONFIG_EXT4_DEBUG is not set

That's why I said they are new messages.

I've just booted 4.1.7 and I get the messages from that kernel too. I wonder if there's a recent fix that has made it
into 4.1.7, but not into 4.2.0. I'll apply Greg's 4.2.1-rc1 patch and see what I get with that.

As the kernel doesn't know which FS your root is, it tries the whole list of filesystems 
(init/do_mounts.c mount_block_root()). Since the removal of ext3, now the ext4 code is responsbile 
for mounting ext3. Since your FS is ext4 and not ext3, the probe for ext3 fails. That's what the 
message tells you. You get these even in previous kernels if you say N to ext3 during config.

If it bugs you, you can add a hint to your kernel command line: rootfstype=ext4
