I'm testing swapout workload in a two-socket Xeon machine. The workload has 10
threads, each thread sequentially accesses separate memory region. TLB flush
overhead is very big in the workload. For each page, page reclaim need move it
from active lru list and then unmap it. Both need a TLB flush.

pageattr-test calls srandom32() once every test iteration.
But calling srandom32() after late_initcalls is not meaningfull.
Because the random states for random32() is mixed by good random numbers
in late_initcall prandom_reseed().
So this removes the call to srandom32().

Hi Greg,
Today's linux-next merge of the driver-core.current tree got conflicts
in 21 files in drivers/i2c between commit 0b255e927d47 ("i2c: remove

Woody,
Any chance you can bisect this? It's not going to be hugely pleasant
(with 11k+ commits in between 3.7 and 3.8-rc1 you'll have to compile
and test at least 14 kernels), but it would help enormously. Of
course, maybe some USB person can guess what would cause the device to
go offline..

Well, *any* other error value is likely a bad choice.

Hi,
I'm Ryo Onodera.
This is a resend for my earlier patch. Because I got no reply, I've
added other people as CC, picking from the commit history of the
relevant file.
I created this very tiny patch to enable /proc/diskstats for /dev/ramX.
I'm contacting Nick Piggin as the maintainer of

Hi Willy et al,
Please consider
f70e957cda22 x86: Don't use the EFI reboot method by default,
2011-07-06
for application to the 2.6.32.y and 2.6.34.y trees. The patch was
applied upstream late in the 3.0 cycle, so newer kernels don't need
it.

__alloc_bootmem_node_high() would panic if it failed allocating, so the fallback
would never get reached. Switch to using __alloc_bootmem_node_high_nopanic().

There's no need to check the result of alloc_bootmem() functions since
they'll panic if allocation fails.

Bootmem alloc functions are supposed to panic if allocation fails unless a
*_nopanic() function is used. However, if slab is available this is not the
case currently, and the function might return a NULL.
Currect it to panic on failed allocations even if slab is available.

Thanks!
but what about 2/3 and 3/3?
I'd like to send the final (and technically trivial) series which
actually turns the filtering on.
