Subject: EXT4: new warnings from 4.3.0-rc2

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
