There are multiple roots to the problems which\nmeans dealing with any of the root problems in isolation is tricky to\njustify on their own and they would still need integration testing. This\npatch series puts together two different patch sets which in combination\nshould tackle some of the root causes of latency problems being reported.\n\nPatch 1 adds a tracepoint for shrink_inactive_list. For this series, the\nmost important results is being able to calculate the scanning/reclaim\nratio as a measure of the amount of work being done by page reclaim.\n\nPatch 2 accounts for time spent in congestion_wait.\n\nPatches 3-6 were originally developed by Kosaki Motohiro but reworked for\nthis series. It has been noted that lumpy reclaim is far too aggressive\nand trashes the system somewhat. As SLUB uses high-order allocations, a\nlarge cost incurred by lumpy reclaim will be noticeable. It was also\nreported during transparent hugepage support testing that lumpy reclaim\nwas trashing the system and these patches should mitigate that problem\nwithout disabling lumpy reclaim.\n\nPatch 7 adds wait_iff_congested() and replaces some callers of\ncongestion_wait(). wait_iff_congested() only sleeps if there is a BDI\nthat is currently congested. Patch 8 notes that any BDI being congested\nis not necessarily a problem because there could be multiple BDIs of\nvarying speeds and numberous zones. It attempts to track when a zone\nbeing reclaimed contains many pages backed by a congested BDI and if so,\nreclaimers wait on the congestion queue.\n\nI ran a number of tests with monitoring on X86, X86-64 and PPC64. Each\nmachine had 3G of RAM and the CPUs were\n\nX86: Intel P4 2-core\nX86-64: AMD Phenom 4-core\nPPC64: PPC970MP\n\nEach used a single disk and the onboard IO controller.
