Only in 2.4.19pre8aa3: 00_compile-nfsroot-1 Only in 2.4.19pre8aa3: 00_initrd-free-2 Only in 2.4.19pre8aa3: 00_ufs-compile-1 Merged in mainline. Only in 2.4.19pre8aa3: 00_cpu-affinity-rml-3 Dropped (collided with o1 and it's not needed). Only in 2.4.19pre8aa3: 00_cpu-affinity-syscall-rml-2.4.19-pre7-1 Only in 2.4.19pre9aa1: 00_cpu-affinity-syscall-rml-2.4.19-pre9-1 Ported to the o1 sched with the -ac patch in rml/sched. Only in 2.4.19pre8aa3: 00_dnotify-cleanup-1 Only in 2.4.19pre9aa1: 00_dnotify-cleanup-2 Just keep the leftover out deletion in -ac. Only in 2.4.19pre9aa1: 00_ext2-ext3-warning-1 Warning when mounting an ext3 as an ext2 from Andrew Morton. Only in 2.4.19pre9aa1: 00_free_pgtable-and-p4-tlb-race-fixes-1 Fix the pagetable freeing races introduced by the speculative random userspace tlb fills of the p4, patch discussed on l-k. Also fix a definitive kernel smp race condition in free_pgtables. Only in 2.4.19pre8aa3: 00_get_pid-no-deadlock-and-boosted-3 Only in 2.4.19pre9aa1: 10_get_pid-no-deadlock-and-boosted-4 Discard the inferior attempt in pre9 and rediff (as Ihno noticed in practice the complexity dominates, if you fill the pid space the fix in mainline is useless anyways). Wonder why this much better fix isn't been merged instead (it is been submitted for both 2.2 and 2.4). This also fix a longstanding fork race present even in 2.2 that can lead to two tasks getting the same pid. Only in 2.4.19pre9aa1: 00_negative-dentry-waste-ram-1 Collect negative dentries after unlink or creat-failure (discussed on l-k, for 2.5 a very-low-prio lru list can be implemented instead). Only in 2.4.19pre8aa3: 00_rcu-poll-5 Only in 2.4.19pre9aa1: 10_rcu-poll-6 Ported to the o1 scheduler, this has a fix in force_cpu_reschedule compared to the rcu-poll patch in 2.5, and also it saves cachelines by colaescing the per-cpu quiescent sequence number in the runqueue structure, the quiescent will be increased at every schedule() call (i.e. every time we reach the quiescent point), so it is optimal to coalesce it in the same cacheline with the other fields later used by schedule(). the per-cpu quiescent++ is the _only_ fixed cost of rcu-poll, this is been a design choice to keep the fast-path overhead as low as possible. Only in 2.4.19pre9aa1: 00_sched-O1-rml-2.4.19-pre9-1.gz 2.5 O1 scheduler from Ingo Molnar backported to 2.4 from Robert Love. Only in 2.4.19pre9aa1: 00_shm_destroy-deadlock-1 Fix SMP deadlock due scheduling with spinlock held in IPC_RMID (fput is a blocking operation). Only in 2.4.19pre9aa1: 00_vm86-pagetablelock-1 Add pagetable lock to the vm86 pagetable walking, from Benjamin LaHaise. Only in 2.4.19pre9aa1: 02_sched-19pre8ac5-1 Use the wq locks so it stays generic and the switch in wait.h doesn't break. From -ac o1 sched comparison. Only in 2.4.19pre9aa1: 02_sched-alpha-1 alpha updates to make o1 working. This is also a good tutorial to port all the other archs. Only in 2.4.19pre9aa1: 02_sched-sparc64-1 Little attempt, only takes care of two bits, still lots of stuff missing for sparc64 and x86-64, they won't compile at the moment. Only in 2.4.19pre9aa1: 02_sched-x86-1 Additional fix for x86 (needed because of the rcu-poll changes to make the runqueue structure visible to the common code). Only in 2.4.19pre8aa3: 05_vm_03_vm_tunables-1 Only in 2.4.19pre9aa1: 05_vm_03_vm_tunables-2 Only in 2.4.19pre8aa3: 05_vm_06_swap_out-1 Only in 2.4.19pre9aa1: 05_vm_06_swap_out-2 Only in 2.4.19pre8aa3: 05_vm_07_local_pages-1 Only in 2.4.19pre9aa1: 05_vm_07_local_pages-2 Only in 2.4.19pre8aa3: 05_vm_08_try_to_free_pages_nozone-1 Only in 2.4.19pre9aa1: 05_vm_08_try_to_free_pages_nozone-2 Only in 2.4.19pre8aa3: 05_vm_09_misc_junk-1 Only in 2.4.19pre9aa1: 05_vm_09_misc_junk-2 Only in 2.4.19pre8aa3: 05_vm_17_rest-4 Only in 2.4.19pre9aa1: 05_vm_17_rest-7 Various random rediffing to sync with the o1 scheduler introduction. Only in 2.4.19pre9aa1: 05_vm_18_buffer-page-uptodate-1 Optimization to avoid losing the page-uptodate information while dropping the bh, from Andrew Morton. Only in 2.4.19pre9aa1: 10_inode-highmem-1 Avoid highmem pagecache to pin inodes in memory undefinitely, if we detect the "pinned inode" condition we shrink the cache. This should fix the last (known :) highmem vm unbalance problem. Only in 2.4.19pre8aa3: 10_numa-sched-18 Dropped in favour of the o1 scheduler, but it's not obsoleted by the o1 scheduler, for istance all the runqueue should go into the zone local memory so even the spinlocks are local etc... Only in 2.4.19pre9aa1: 10_o1-sched-64-cpu-1 Fix 64bit bug in o1 scheduler. Only in 2.4.19pre9aa1: 10_o1-sched-fixes-1 Other o1 sched fixes. Only in 2.4.19pre9aa1: 10_o1-sched-nfs-1 Fix nfs to compile with the o1 scheduler. Only in 2.4.19pre9aa1: 10_parent-timeslice-10 Only in 2.4.19pre8aa3: 10_parent-timeslice-9 Port this longstanding scheduler fix in the "share" timeslice algorithm on top of the o1 scheduler (with o1 the coding of the algorithm changed but the bug was stll there). This bug is been noticed in real life workloads that rendered the machine not interactive during intensive bash/exec/wait workloads. Only in 2.4.19pre8aa3: 10_tlb-state-2 Only in 2.4.19pre9aa1: 10_tlb-state-3 Mainline patch is inferior, backedout and resurrected this one. Only in 2.4.19pre8aa3: 20_share-timeslice-2 Obsoleted by the o1 scheduler, I missed the code in wake_up_forked_process, I didn't verified that it really works as expected in practice with gdb but the code looked ok. We'll see with the next round of benchmarks from Randy (the fact 2.5 wasn't forking as fast as previous -aa make me to think it might be related to an difference here). Only in 2.4.19pre8aa3: 30_dyn-sched-6 Obsoleted in favour of o1 that also provides similar dynamic priority. Only in 2.4.19pre8aa3: 50_uml-patch-2.4.18-25.gz Only in 2.4.19pre9aa1: 50_uml-patch-2.4.18-30.gz New patch from Jeff. NOTE: this compiles with o1 but it hangs sometime until you press a character on the konsole and then it restarts like if it didn't hanged, I checked schedule_ticks keeps running and that rq->nr_running is zero, so I'm not sure what's wrong at the moment. Could even be a bug between -29 and -30, I tested only -30 with o1, OTOH -29 was working fine w/o o1. Jeff could you give a spin to 2.4.19pre9aa1 and see what's wrong with uml? (sounds like a problem with the uml internals that you certainly know better than anyone else :) Only in 2.4.19pre8aa3: 51_uml-ac-to-aa-8 Only in 2.4.19pre9aa1: 51_uml-ac-to-aa-9 Only in 2.4.19pre9aa1: 51_uml-o1-1 Only in 2.4.19pre8aa3: 52_uml-sys-read-write-1 Only in 2.4.19pre9aa1: 52_uml-sys-read-write-2 Only in 2.4.19pre8aa3: 57_uml-dyn_sched-1 Only in 2.4.19pre8aa3: 59_uml-yield-1 Only in 2.4.19pre9aa1: 59_uml-yield-2 Various updates to compile, in particular with o1. Only in 2.4.19pre8aa3: 60_show-stack-1 Only in 2.4.19pre9aa1: 62_tux-dump-stack-1 Use dump_stack instead.
