src/sys/kern: sys_ptrace_common.c
Log Message:
Fix kernel panic triggered with LLDB
PT_SETSTEP and PT_CLEARSTEP in the current design must unlock proc_lock and
t->p_lock. These functions use lwp_delref() for a tracee with more than one
LWP. This function internally lock (t->)p_lock and this is lock against
self.
There are coming new ATF test with PT_*STEP with multiple LWPs to catch
these bugs in future changes.
