Patches
diff-cpt-comp-errno-fix-20060424
Patch from Dmitry Mishin <dim@openvz.org>:
Fixed cpt compilation on ia32 with gcc 4.0.2
diff-cpt-comp-fix-20060424
Patch from Dmitry Mishin <dim@openvz.org>:
Fixed compilation for CONFIG_VZ_CHECKPOINT=y
- static eventpoll_ops
- strut for __put_namespace
- common files for cpt and rst modules
- emt64 kernel thread creation
diff-cpt-comp-htlb-ipv6-fix-20060426
Patch from Dmitry Mishin <dim@openvz.org>:
[CPT] Fixed compilation with CONFIG_HUGETLB and CONFIG_IPV6 enabled.
diff-fairsched-20060502
Patch from Kirill Korotaev <dev@openvz.org>:
Fair cpu scheduler
diff-fairsched-init-boot-20060510
Patch from Pavel Emelianov <xemul@openvz.org>:
Initialize vcpus for idle_vsched and default_vsched in migration_call
Normally this should be done after CPU_UP_PREPARE event, but some arches (i386) call init_idle() before it, so init vcpus there as well.
This patch fixes boot process for x86_64 smp kernel.
diff-fairsched-ppc-task-cpu-20060502
Patch from Kirill Korotaev <dev@openvz.org>:
Fix usage of task_cpu on powerpc.
diff-fairsched-up-comp-20060502
Patch from Pavel Emelianov <xemul@openvz.org>:
Fixed fairsched compilation for UP
diff-fairsched-vcpu-del-fix-20060503
Patch from Pavel Emelianov <xemul@openvz.org>:
Don't migrate migration thread from dying vcpu on VPS stop.
Otherwise on destroying the last cpu destination will be NR_CPUS cpu and it will cause an OOPs in __migrate_task() (#61877).
diff-fairsched-yield-20060502
Patch from Kirill Korotaev <dev@openvz.org>:
Fix vsched_del_vcpu to work under lock_kernel()
vzioctls are called under lock_kernel() as all other ioctl's. This lead to the fact that scheduler code can do cpu_relax() with lock_kernel() being held, which isn't good anyhow. I replaced one such non-fatal cpu_relax() with yield(). It is not fatal since vcpu has no more tasks and should be switched from at this moment.
diff-faudit-statfs-fix-20060421
Patch from Pavel Emelianov <xemul@openvz.org>:
Compat layer in 64bit systems didn't call faudit on statfs calls.
Now faudit uses struct kstatfs for patching statfs data and compat layer uses it.
diff-lockkernel-20060502
Patch from Kirill Korotaev <dev@openvz.org>:
Remove lock_kernel() from vzioctls, since nothing in our code requires it...
diff-merge-2.6.16.13-20050504
Patch from OpenVZ team <devel@openvz.org>:
Merged 2.6.16.13 from /linux/kernel/git/stable/linux-2.6.16.y
diff-merge-2.6.16.15-20060510
Patch from OpenVZ team <devel@openvz.org>:
Merged 2.6.16.15 from /linux/kernel/git/stable/linux-2.6.16.y
diff-merge-2.6.16.9-20060424
Patch from OpenVZ team <devel@openvz.org>:
Merge 2.6.16.9 from /linux/kernel/git/stable/linux-2.6.16.y
diff-oops-decode-fix
Patch from Pavel Emelianov <xemul@openvz.org>:
Some fixes for disabling of decoding calltraces
- some places were missed in emt64
- make it "on" by default
diff-sched-stats-20060502
Patch from Pavel Emelianov <xemul@openvz.org>:
Scheduler tasks statistics needed with fairsched.
Adds percpu counters for number of running, sleeping, stopped etc tasks and updates them in proper places. nr_xxx() functions are patched to use them.
Patch is needed for fairsched to calculate these numbers correctly.
diff-ubc-cache-counter-free-20060503
Patch from Pavel Emelianov <xemul@openvz.org>:
Free ubc cache counters on cache destroy.
diff-ubc-mremap-fix-20060503
Patch from Pavel Emelianov <xemul@openvz.org>:
Charge correct size in sys_mremap.
Since only (new_len - old_len) region is added to address space this very size should be charged, not the whole new_len.
diff-ubc-pbc-comp-fix-20060422
Patch from Pavel Emelianov <xemul@openvz.org>:
Compilation without USER_RSS_ACCOUNTING fix.
ub_init_pbc() is in kernel/ub/ub_page_bc.c which is compiled under CONFIG_USER_RSS_ACCOUNTING, not CONFIG_USER_RESOURCE
diff-ubc-vmrss-fix-20060421
Patch from Pavel Emelianov <xemul@openvz.org>:
Handle of mapping (with vma merging) of /dev/zero
- lost ub_unused_privvm_dec in zeromap_pte_range caused "ub helds xxx in unused_privvmpages on put" message
- do_mmap_pgoff can perform such a thing:
- # allocate a new VMA
- # populate it with pages via file->f_ops->mmap
- # try to merge this VMA with vma_merge
- # free VMA without inserting it in to list
- # as the result the expanded with vma_merge vm_area doesn't account populated rss. So vma_rss counter must be tuned in do_mmap_pgoff.
diff-ubc-xip-include-20060428
Patch from Pavel Emelianov <xemul@openvz.org>:
Add missed include in mm/filemap_xip.c
diff-ve-higetlb-fix-20060506
Patch from Pavel Emelianov <xemul@openvz.org>:
Fix hugetlb compilation for CONFIG_VE=n case
diff-ve-kstat-fix-20060424
Patch from Pavel Emelianov <xemul@openvz.org>:
Fix mm/vmscan.c compilation
CC mm/vmscan.o mm/vmscan.c: In function `refill_inactive_zone': mm/vmscan.c:1246: warning: ISO C90 forbids mixed declarations and code
diff-ve-netdev-comp-fix-20060424
Patch from Dmitry Mishin <dim@openvz.org>:
Fixed compilation for CONFIG_VE_NETDEV=y
diff-venet-resetsaddr-20060420
Patch from Denis Lunev <den@openvz.org>:
This patch sets skb destination address as a source in ip_send_reply (TCP reset)
diff-ve-nf-comp-fix-20060424
Patch from Dmitry Mishin <dim@openvz.org>:
Fix compilation for CONFIG_VE_IPTABLES=y
diff-ve-sched-stat-iowait-20060417
Patch from Dmitry Mishin <dim@openvz.org>:
Per VPS i/o wait time was accounted wrongly as presense of uninterruptible tasks, not those in IO wait state.
