When a process in the kernel space is holding a spin_lock , the process cannot be preempted due to any of the following conditions : When the time-slice of the process gets exhausted When a high priority process becomes runnable When an interrupt occurs However the process can yield the processor if it blocks, sleeps, or explicitly call schedule() . Is my understanding correct? When a process in the kernel space is holding a mutex_lock , can the process be preempted due to the above conditions listed as 1, 2 and 3.

Linux Kernel Preemption during spin_lock and mutex_lock

When a process in the kernel space is holding a spin_lock, the process cannot be preempted due to any of the following conditions :

However the process can yield the processor if it blocks, sleeps, or explicitly call schedule(). Is my understanding correct?
