I had been hoping that the people who care about SMT and NUMA performance would have some results by now but all seems to be silent. I do not wish to merge these up until the big-iron guys can say that they suit their requirements, with a reasonable expectation that we will not need to churn this code later in the 2.6 series. So. If you have been testing, please speak up. If you have not been testing, please do so. - Major surgery against the pagecache, radix-tree and writeback code. This work is to address the O_DIRECT-vs-buffered data exposure horrors which we've been struggling with for months. As a side-effect, 32 bytes are saved from struct inode and eight bytes are removed from struct page. This change will break any arch code which is using page->list and will also break any arch code which is using page->lru of memory which was obtained from slab. It seems to work OK here, but I suggest people not rush out and convert all of the corporate finance department's servers to 2.6.4-mm1. The basic problem which we (mainly Daniel McNeil) have been struggling with is in getting a really reliable fsync() across the page lists while other processes are performing writeback against the same file. It's like juggling four bars of wet soap with your eyes shut while someone is whacking you with a baseball bat. Daniel pretty much has the problem plugged but I suspect that's just because we don't have testcases to trigger the remaining problems. The complexity and additional locking which those patches add is worrisome. So the approach taken here is to remove the page lists altogether and replace the list-based writeback and wait operations with in-order radix-tree walks. The radix-tree code has been enhanced to support "tagging" of pages, for later searches for pages which have a particular tag set. This means that we can ask the radix tree code "find me the next 16 dirty pages starting at pagecache index N" and it will do that in O(log64(N)) time. This affects I/O scheduling potentially quite significantly. It is no longer the case that the kernel will submit pages for I/O in the order in which the application dirtied them. We instead submit them in file-offset order all the time. This is likely to be advantageous when applications are seeking all over a large file randomly writing small amounts of data. I haven't performed much benchmarking, but tiobench random write throughput seems to be increased by 30%. Other tests appear to be unaltered. dbench may have got 10-20% quicker, but it's variable. There is one large file which everyone seeks all over randomly writing small amounts of data: the blockdev mapping which caches filesystem metadata. The kernel's IO submission patterns for this are now ideal. Because writeback and wait-for-writeback use a tree walk instead of a list walk they are no longer livelockable. This probably means that we no longer need to hold i_sem across O_SYNC writes and perhaps fsync() and fdatasync(). This may be beneficial for databases: multiple processes writing and syncing different parts of the same file at the same time can now all submit and wait upon writes to just their own little bit of the file, so we can get a lot more data into the queues. It is trivial to implement a part-file-fdatasync() as well, so applications can say "sync the file from byte N to byte M", and multiple applications can do this concurrently. This is easy for ext2 filesystems, but probably needs lots of work for data-journalled filesystems and XFS and it probably doesn't offer much benefit over an i_semless O_SYNC write. - Dropped the hotplug CPU patches: bits of them were merged into Linus's kernel and things broke. - Various little fixes as usual.
