Subject: mixing interupts and threads.

Hello All ,
I've a few questions.
1. Lets suppose i've some critical section and it is synchronized with
locks. A thread came and it's execution is in the middle of critical
section, at this time an interrupt was occurred which also executes
critical section. As interrupts can't wait on any lock it will get lock
and try to execute the critical section and above thread was not yet
completed. So inconsistency . How this was handled in Linux.
2.Some process is running in kernel mode, at this a kill was sent to
this process, does this signal will delivered to the process while it is
in kernel mode.
And also please provide some links how threads ,signals and interrupts
will be mixed.
Regards,
Ravikumar.
