Hi,
I think I found a possible bug on file signal.h.
The problem comes when you define a struct sigaction on a user program
and then you use the function sigaction to remap a signal handler (in
my case a page_fault) for my own function, this system call is

hai all,
Is it possible to call call_usermodehelper from interrupt context.
Of course not! I've seen this message before. Either it's a joke
or you have no clue about what interrupts are.

This can be asking for trouble too (auto negotiation is often buggy).
What if you hard set them both to 100/full?

The attached patch was sent for 2.6.10 but the kernel was
never updated. The kernel used to be compiled with -Wshadow
and would catch these problems. It no longer is (and it
should be).
I attached it so the M$ mail-sender doesn't dork with
white-space.
