distinguish between user mode and kernel mode?
Answer Posted / narendrasairam immadi
When a process is in user space, its system calls are being
intercepted by the tracing thread. When it's in the kernel,
it's not under system call tracing. This is the distinction
between user mode and kernel mode.
The transition from user mode to kernel mode is done by the
tracing thread. When a process executes a system call or
receives a signal, the tracing thread forces the process to
run in the kernel if necessary and continues it without
system call tracing
