The patchset contains ... oh hell, anything I feel like putting in it. It's meant to be pretty stable - performance should be better than mainline, particularly on larger machines. 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/2.6.1-rc1/patch-2.6.1-rc1-mjb1.bz2 Since 2.6.0-mjb2 (~ = changed, + = added, - = dropped) Notes: Now includes kexec and the new kgdb-over-ethernet code ... please test! Sound under xmms, and other code that uses OSS emulation interfaces to ALSA drivers should sound a whole load better than mainline with this release. ----------------------------------------------------------------------- Now in Linus' tree: - vm86_sysenter_fix Brian Gerst Re-enable sysenter after task switch - readahead_fixes Ram Pai Fix performance bugs in readahead - readahead_simplfiy Ram Pai Simplify the readahead code - slab_reclaim_accounting Manfred Spraul Fix slab reclaim accounting Dropped: New: + smp_boot_id Martin J.
