</div>

==== diff-cpt-comp-htlb-ipv6-fix-20060426 ====

<div class="change">
Patch from Dmitry Mishin <dim@openvz.org>:<br/>
[CPT] Fixed compilation with CONFIG_HUGETLB and CONFIG_IPV6 enabled.
</div>

==== diff-fairsched-20060502 ====
<div class="change">
Patch from Kirill Korotaev <dev@openvz.org>:<br/>
Fair cpu scheduler
</div>

==== diff-fairsched-init-boot-20060510 ====
<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
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.
</div>
==== diff-fairsched-ppc-task-cpu-20060502 ====

<div class="change">
Patch from Kirill Korotaev <dev@openvz.org>:<br/>
Fix usage of task_cpu on powerpc.
</div>

==== diff-fairsched-up-comp-20060502 ====
<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
Fixed fairsched compilation for UP
</div>

==== diff-fairsched-vcpu-del-fix-20060503 ====

<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
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).
</div>

==== diff-fairsched-yield-20060502 ====
<div class="change">
Patch from Kirill Korotaev <dev@openvz.org>:<br/>
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.
</div>

==== diff-faudit-statfs-fix-20060421 ====
<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
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.

{{Bug|142}}.
</div>

==== diff-lockkernel-20060502 ====
<div class="change">
Patch from Kirill Korotaev <dev@openvz.org>:<br/>
Remove lock_kernel() from vzioctls, since nothing in our code requires it...
</div>

==== diff-merge-2.6.16.13-20050504 ====

<div class="change">
Patch from OpenVZ team <devel@openvz.org>:<br/>

* make it "on" by default
</div>

==== diff-sched-stats-20060502 ====
<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
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.
</div>

<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
Free ubc cache counters on cache destroy.

==== diff-ubc-mremap-fix-20060503 ====
<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
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.

{{Bug|141}}.
</div>

==== diff-ubc-pbc-comp-fix-20060422 ====
<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>
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
</div>

==== diff-ubc-vmrss-fix-20060421 ====
<div class="change">
Patch from Pavel Emelianov <xemul@openvz.org>:<br/>

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.
