I have a truly marvellous patch that fixes the bug which this

Hi All,
I am running a light weight kernel named kitten in QEMU-KVM which uses
LWIP (Light Weight TCP/IP) stack for networking. I am trying to fine
tune this LWIP but I am now facing an issue regarding delayed packet
reception. Basically I wrote a small pingpong program where master
sends a data
The following series is the four patches Dave Hansen had queued for test
as mentioned last week in the thread:
[PATCH] kvm: make mmu_shrink() fit shrinker's requirement
Last week just before leaving for vacation Dave had noted in that thread
that these four were ready to merge based on our perf
From: Dave Hansen d...@linux.vnet.ibm.com
[PATCH 1/4 v2] kvm: abstract kvm x86 mmu-n_free_mmu_pages
First of all, I think free is a poor name for this value. In
this context, it means, the number of mmu pages which this kvm
instance should be able to allocate. To me, free implies
much more
From: Dave Hansen d...@linux.vnet.ibm.com
[PATCH 2/4 v2] kvm: rename x86 kvm-arch.n_alloc_mmu_pages
Again, I think this is a poor choice of names. This value truly
means, the number of pages which _may_ be allocated. But,
reading the value, n_alloc_mmu_pages, I'm unable to think of
anything it
From: Dave Hansen d...@linux.vnet.ibm.com
[PATCH 3/4 v2] kvm: replace x86 kvm n_free_mmu_pages with n_used_mmu_pages
I think doing this makes the code much more readable. That's
borne out by the fact that this patch removes code. used
also happens to be the number that we need to return back
From: Dave Hansen d...@linux.vnet.ibm.com
[PATCH 4/4 v2] kvm: create aggregate kvm_total_used_mmu_pages value
Note: this is the real meat of the patch set. It can be applied up
to this point, and everything will probably be improved, at least
a bit.
Of slab shrinkers, the VM code says:
*
Add LDS/LES/LFS/LGS/LSS instruction emulation.
