H A D | kern_ktrace.c | diff 219311 Sat Mar 05 18:46:01 MST 2011 dchagin Partially reworked r219042. The reason for this is a bug at ktrops() where process dereferenced without having a lock. This might cause a panic if ktrace was runned with -p flag and the specified process exited between the dropping a lock and writing sv_flags. Since it is impossible to acquire sx lock while holding mtx switch to use asynchronous enqueuerequest() instead of writerequest(). Rename ktr_getrequest_ne() to more understandable name [1].
