Subject: Re: [PATCH] fs-writeback: fix NULL pointer dereference in, __mark_inode_dirty
Date: Thu, 10 Mar 2011 11:39:46 +0100 [thread overview]

I ran into the same problem and successfully applied your fix.
I was able to reproduce this panic and bisected it to the following commit:
commit aaead25b954879e1a708ff2f3602f494c18d20b5
Author: Christoph Hellwig <hch@lst.de>
Date: Mon Oct 4 14:25:33 2010 +0200
writeback: always use sb->s_bdi for writeback purposes
The steps to reproduce it on my test system (T60p with Intel Core Duo) were.
- /dev/sdb is an USB stick with partition sdb1 formatted as ext2
- mount /dev/sdb1 /mnt
- cat > /mnt/foo
- now press return some times
- remove stick
- press return, panic takes place
Hope this helps fixing the problem,
Torsten
