FYI: the next things I will try to concentrate on the next days are:
1) get_swap_entry collecting exclusive swapcache pages
2) Hugh's locking cleanups
3) Marcelo's vm patches
4) rcu, Dipankar, could you send me your latest version, the design that we
agreed that only adds a per-cpu sequence number inc (not a branch)
in schedule?
5) listening to the softirq patches, still I'd be curious to see the raw
number with only the deschedule logic, just too see the order of
magnitude of overhead caused by the suprious rescheduling, yes when
there's no softirq pending a ksoftirqd reschedule is _literally_ suprious
Thanks to all but especially to Linus and Al for fixing up the aliasing
issues introduced with the blkdev-pagecache during pre[123]! I wouldn't
been able to cover everything myself in such a short timeframe, so I
really appreciated that.
Only in 2.4.11pre3aa1: 00_backout-2.4.11pre1-1
Resurrect some bit like O_DIRECT and drop the fragile vm_swap_full
logic, the plan is to make get_swap_page able to collect exclusive swap
cache pages. Hugh's patches are pending, they changes locking so they're
not included until I'll check them in detail.
Only in 2.4.11pre3aa1: 00_binfmt-elf-checks-1
Rest of the missing checks.
Only in 2.4.10aa1: 00_enable-apic-1
Dropped.
Only in 2.4.11pre3aa1: 00_highmem-deadlock-1
Finegrined highmem deadlock fix, now if we go creating bounce buffers
while we locked down buffers that aren't in the I/O queue yet, we
set the pending_io bitflag on those locked buffers to make sure we
won't deadlock on them while allocating the bounce pages.
Only in 2.4.10aa1: 00_lvm-1.0.1-rc2-2.bz2
Only in 2.4.11pre3aa1: 00_lvm-1.0.1-rc4-1.bz2
Only in 2.4.11pre3aa1: 10_lvm-incremental-1
Picked last update from www.sistina.com and extracted the incremental
changes into a separate patch to make easier furture merging.
Only in 2.4.11pre3aa1: 00_netconsole-2.4.10-C2
Only in 2.4.10aa1: 00_netconsole-code-1
Only in 2.4.10aa1: 00_netconsole-misc-1
Upgrade to -C2 from www.redhat.com/~mingo/ .
Only in 2.4.11pre3aa1: 00_o_direct-1
O_DIRECT updates after the blkdev physical address space fixes.
Only in 2.4.10aa1: 00_rwsem-fair-20-recursive-2
Only in 2.4.11pre3aa1: 00_rwsem-fair-20-recursive-4
Rediffed, and fixed ppc compilation.
Only in 2.4.11pre3aa1: 00_spinlock-cacheline-1
Cacheline align a few critical spinlocks from Juergen Doelle.
Only in 2.4.11pre3aa1: 00_tcp-nagle-1
nagle TCP/IP fixes extracted from the TUX patch downloadable at
www.redhat.com/~mingo/ .
Only in 2.4.10aa1: 00_vm-tweaks-1
Only in 2.4.11pre3aa1: 00_vm-tweaks-3
Rest of the vm-tweaks not merged because of disagreement. I see
Linus's point but without those swap behaviour sucks. For now
I left them since they're well tested, I will look more into this
shortly.
Only in 2.4.11pre3aa1: 10_compiler.h-1
Move #include <linux/compiler.h> into include/linux/kernel.h to avoid
all the present/future compilation troubles. Assume likely/unlikely
are always available in all kernel code.
Only in 2.4.10aa1: 10_highmem-debug-3
Only in 2.4.11pre3aa1: 10_highmem-debug-4
Rediffed.
Only in 2.4.11pre3aa1: 50_uml-patch-2.4.10-5.bz2
Only in 2.4.10aa1: 50_uml-patch-2.4.9-8-1.bz2
