Hi All,

What is the meaning of user_mode(regs) macro ?  What does it do ?
This macro used in many files in kernel like signal.c, trap.c, process.c
files.
>From the code it looks like it checks is in USER mode or KERNEL mode, but
still not clear on usage and implementation of this macro.

Thanks.

Regard,
Sumeet
