Subject: Re: [PATCH v3]Ext4: journal credits reservation fixes for DIO,
	fallocate and delalloc writepages

I'm noticing that when I reboot, presumably either just before or just
after remounting the filesystem read-only, I'm getting a whole series
of

ext4_da_writepages: Not enough credits to flush N pages

.. where N is mostly 1, but occasionally will be 2.

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.
