Hi Davide,

Hi,
Looking at the tlb_flush code path and its co-relation with
ARCH_FREE_PTE_NR, on x86-64 architecture. I think we still don't use
the ARCH_FREE_PTE_NR of 5350 as the caching value for the mmu_gathers
structure, instead fallback to using 506 due to some typo errors in
the code.

Now we have high res timers on ppc64 I thought Id test them. It turns
out compat_sys_nanosleep hasnt been converted to the hrtimer code and so
is limited to HZ resolution.
The follow patch converts compat_sys_nanosleep to use high res timers.

Hi Andrew,
While running regular cpu-offline tests on 2.6.23-mm1, I

It was triggered because some of the per-cpu counters and thus
their locks are accessed from IRQ context.
This can cause a deadlock if it interrupts a cpu-offline thread which

You obtain the latter with vmalloc_user(); so far, so good. Then you have

The kernel newbies community often gets inquiries from CS students who
need a project for their studies and would like to do something with
the Linux kernel, but would also like their code to be useful to the
community afterwards.
In order to make it easier for them, I am trying to put together a

Good idea, I had considered that

Hi linux-kernel,
[1.] One line summary of the problem:
kernel memory subsystem incorrectly invokes OOM killer under certain situations
[2.] Full description of the problem/report:
My guess is that whatever invokes the OOM killer is incorrectly

Hello,
I posted this question at comp.linux.misc and where told this would be a better

I would like to do a internship in the field of the Linux kernel.
Can someone tell me where to find a list of companies (don't matter in which
country) that employ kernel developers?
