While running 2.6.7 on my Amiga, I got:

Not even atomic allocations memory are allowed to consume all memory.
A small amount is reserved for memory freeing (which sometimes
requires initial memory allocations).
The message should be harmless.

Yep, the files I was copying got copied correctly.

Since atomic allocations by definition need to be able to cope with
failure, how about a patch like this to not warn for this common and
legit case?

CC'ed Andrew: I think it's his baby.
I guess we're at the point where we should quiet down things like
this. Although order-0 atomic allocation failures are pretty rare,
I'd consider leaving them in. Maybe a CONFIG option?

While testing linux-iscsi-4.0.1.1 driver on linux kernel version 2.6.3, my
system's console was floded with follwoing message:
"page allocation failure. order:0, mode:0x20"
Is this a known problem in linux kernel version 2.6.x ?
Is there any patch available for this problem ?
