. Various fixes to various things.
. Spent some time tuning up 2.5's StupidSwapStorm throughput. It's on par with 2.4 for single-threaded things, but not for multiple processes.
This is because 2.4's virtual scan allows individual processes to hammer all the others into swap and to make lots of progress then exit. In the 2.5 VM all processes make equal progress and just thrash each other to bits.
This is an innate useful side-effect of the virtual scan, although it may have significant failure modes. The 2.5 VM would need an explicit load control algorithm if we care about such workloads.
. Included a patch to fix the inodes-pinned-by-highmem-pagecache problem. I'm not 100% happy with this yet - in some tests the VM is reclaiming tons of inodes but slab memory isn't decreasing because of slab fragmentation. Probably we need to take the overall slab occupancy into account there.
But that's a performance thing, not a stability thing.
. Uploaded patch-scripts-0.4 to http://www.zip.com.au/~akpm/linux/patches/patch-scripts-0.4/ This contains some new commands from Stephen Cameron and myself:
export_patch, import_patch, tag-series
They are described in docco.txt.
Since 2.5.44-mm5:
+set_page_dirty-pf_memalloc.patch
Fix the indirect-blocks-never-get-written bug
-deferred-lru-add-fix.patch
Junk. Dropped.
+blkdev_get_block-fix.patch
Fix premature -EIO from blkdev_get_block.
+radix-tree-full-search.patch
Fix the last bug in radix_tree_gang_lookup()
+lru_add_active.patch +pages-on-the-right-list.patch +swapin_readahead-lru_drain.patch +swapcache-pages-inuse.patch +larger-page_cluster.patch
Swap stuff
