[writeback] 6903673566d: +2.5% fileio.requests_per_sec

by Fengguang Wu

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 git://bee.sh.intel.com/git/wfg/linux-devel.git jan-dirty-list commit 6903673566d0289680e593dac088c787d119b067 ("writeback: Replace several writeback lists with inode tagging") 836ecc5f024669e 6903673566d0289680e593dac --------------- ------------------------- 6526 ~ 0%
