Hi Mulyadi,
How SIGKILL is handle by Kernel?
Does SIGKILL SIGTSTP handled separately than the rest of the signals?

When you malloc a memory or mmap a MAP_ANON memory, it is virtually

The page fault handler zeroes those memory and hands it to the process.

Hi All,
Can anyone clarify that when should I use _GPL and when not ?
Is there a policy like for new code, it must be _GPL ?
I see in kernel many places _GPL used like EXPORT_SYMBOL_GPL( ), but many
places only EXPORT_SYMBOL( ).

Hi All,
Man page of waitpid give expansion with example on how to send SIGSTOP,
SIGCONT and SIGKILL/SIGTERM to a running process. If we don't implement waitpid
system call we will not be able to observer the states of process when we issue
a signal to running process.

Yes you are right.
Each architecture implements clear_page() differently. Some may just use
memset. Some may use architecture specific instructions to perform the
zero-ing faster.
I guess x86's fast_clear_page does that.
