jhb 3d7b05e4b2 MFC: Close some races between procfs/ptrace and exit1() by changing ... exit1() to block until any current PHOLD's are released. This includes Simplifying the cleanup code in kern_ptrace() and removing the now unnecessary vmspace ref counting magic from proc_rwmem(). Also, the locking for ptrace_single_step(), ptrace_set_pc(), and ptrace_clear_single_step() have been fixed to be consistent across the tree. Approved by: re (scottl)		2006-03-07 18:08:09 +00:00
