Subject: Re: [PATCH v3]Ext4: journal credits reservation fixes for DIO, fallocate and delalloc writepages
Date: Fri, 1 Aug 2008 15:29:47 -0400 [thread overview]
Message-ID: <20080801192947.GA8789@mit.edu> (raw)
In-Reply-To: <1217383118.27664.14.camel@mingming-laptop>
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.
