I'm not sure why this is happening; I did run sync before rebooting,
and I haven't noticed any files written just before the reboot getting
corrupted, but there is something strange happening here.

I instrumented the check, and it is returning an error -30 --- EROFS.

So it's not the fault journal credits patch, but I'm a bit concerned
why ext4_da_writepages is getting called right before the system is
rebooted, and presumably after the filesystem is remounted read/only.
