sys/kern kern_mac.c
Log:
Close a race in process label changing opened due to dropping the
proc locking when revoking access to mmaps. Instead, perform this
later once we've changed the process label (hold onto a reference
to the new cred so that we don't lose it when we release the
process lock if another thread changes the credential).
