Dave has been stressing some XFS patches of mine that remove the XFS internal writeback clustering in favour of using write_cache_pages.Against what kernel? 2.6.38 was a disaster for reclaim I've been finding out this week. I don't know about 2.6.38.8. 2.6.39 was better.
The patch series is against current 3.0-rc, I assume that's what Dave tested as well.
I'm assuming "test 180" is from xfstests which was not one of the tests I used previously. To run with 1000 files instead of 100, was the file "180" simply editted to make it look like this loop instead?
