The patchset contains mainly performance, scalability and NUMA stuff, and anything else that stops things from irritating me. It's meant to be pretty stable, not so much a testing ground for new stuff. I'd be very interested in feedback from anyone willing to test on any platform, however large or small. ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/2.6.0-test11/patch-2.6.0-test11-mjb3.bz2 Since 2.6.0-test11-mjb2 (~ = changed, + = added, - = dropped) Notes: Now in Linus' tree: Dropped: - page_lock William Lee Irwin Conditionally convert mapping->page_lock back to an rwlock (conflicts with text replication) New: + poll_8139too_fix akpm Fix a locking bug + lotsa_sds Badari Enable lots of scsi disks + readahead_fixes Ram Pai Fix performance bugs in readahead + readahead_simplfiy Ram Pai Simplify the readahead code + schedstat_arches Rick Lindsley Make schedstats support PPC, PPC64, x86_64 as well as ia32 + user_text_replication Dave Hansen Replicate read-only user text. + amd_installkernel Martin J.
