Hi, I am writing a DLKM for HPUX 11.0 on PA-RISC 64 bits.
I was wondering whether kernel thread stack addresses are global
around the kernel.
For example, suppose a user send an IOCTL call to my driver, on the
stack
I put a a b_sema variable on the stack, and then call the timeout
routine with
this variable parameter. When the timeout callback expires on another
arbitrary thread, will the pointer be valid and the timeout routine
could signal the
semaphore?

Regards.
ERAN.
