Modified files:
sys/kern kern_exec.c
Log:
Conditionally acquire Giant when dropping a reference on the ktrace vnode
during execve() when turning off tracing due to executing a setuid binary
as non-root. Previously this could fail to acquire Giant and fail an
assertion if the ktrace file was on a non-MPSAFE filesystem and the
executable was on an MPSAFE filesystem.
