I used rt_mutex_lock to protect
one critical section in softirq-rx code . There is some kernel crash
happens in the critical section .
In my OOPs analysis i found that ..
PC- > my function code in critical section
LR -> rt_mutex_unlock .
Why LR is rt_mutex unlock ? Before unlocking , preemption can happen ?
Thanks,
Ratheesh
