You need to post more than 4 lines of code to get help, e.g. where is
this with respect to your "sleeping" code?
The problem is that even if I do ctrl-Z on the key board, abouve code
returns and user process stops.
What do you expect to happen? How do you know your user process (that
you suspended) is executing in your kernel module? I can't tell,
because you didn't paste the relevant code.
What is the correct way of handling this ? should I check for specified
signals, e.g. man 7 signal says that following signal should kill the
process and some of them shuold also do core
What are you actually trying to do? Please make it clear and concise,
and post it along with all of the code.
Thanks,
Nish
