 Committed By:  martin
 Date:          Mon Feb 20 12:19:56 UTC 2012
 Modified Files:
        src/sys/kern: kern_exec.c
 Log Message:
 More posix_spawn fallout:
 Fix a kmem_alloc() call with zero size (PR kern/46038), allow file actions
 to be passed, even if empty.
 Rearange p_reflock locking for the child, avoid a double free in an
 error case, avoid a memory leak in another error case - all pointed out
 by yamt.
 During blocking operations early in the child borrow the kernel vmspace
 (as suggested by yamt).
