DragonFly-2.3.0.890.g9d7a6 master sys/kern kern_exit.c kern_lock
commit 9d7a637e6808396b43ab61ee634665b49704f752
Author: Aggelos Economopoulos <aoiko@cc.ece.ntua.gr>

lock around accesses to uidinfo and varsymset
- add ->vx_lock to protect the varsymset fields
- add ->ui_lock to protect the rest of the fields in uidinfo
- protect the uidinfo hash
- the varsym*() syscalls are now mpsafe
This is obviously performance-irrelevant, but it allows
access to uidinfo without the BGL.
