I'm seeing a regression with current kernel git head when using NFS-mounts.
Architecture in my case is parisc, although I don't think that this is relevant.
At least kernel 3.10 (and I think 3.11) didn't showed that problem.
The symtom is, that "top" shows high usage of either kswapd0 or kswapd1.

As such it's in principle possible to provide a lot more UUIDs (if needed) per
time than in userspace.
Additionally a mutex takes care of the proper locking against a mistaken
double creation of UUIDs for simultanious running processes.

Hi Cyrill,

err1 is used only when CONFIG_HP300 is defined and in the parisc-case you

Hello Cyrill,
thanks a lot for the patch.
I've applied it to the PARISC-Linux git tree:
http://git.parisc-linux.org/?p=linux-2.6.git;a=commit;h=2b1f35b1cdec70c3a0ee2d4174668597355b6041
Your patch made me aware of an unitialized spinlock in the code as well:
http://lists.parisc-linux.org/pipermail
On PARISC-Linux the stack grows up, which is why on this platform
CONFIG_STACK_GROWSUP is #defined by default.
The patch below allows shmat() to map the requested memory region on this
platform directly below the start of the stack, without the need to reserve
memory for a downward-growing stack
