Hi,

I've completed bisection process. It looks like kernel up to

704b2907 "xfs: register the inode cache shrinker before quotachecks"

is good and first bad commit is:

0e6e847f "xfs: stop using the page cache to back the buffer cache"

I double tested it - 704b2907 can do 60+ loops of xfsdump without any
trouble and 0e6e847f breaks in <10 iterations.

Can I do something more to help?
