Subject: [writeback] 6903673566d: +2.5% fileio.requests_per_sec
Hi Jan,
I tried your writeback dirty list patchset and noticed some ups/downs.
The main performance changes are
1) +2.5% fileio.requests_per_sec
2) -7.1% iostat.md0.wkB/s

commit 6903673566d0289680e593dac088c787d119b067 ("writeback: Replace several writeback lists with inode tagging")
