CVS commit: src/sys/kern

Module Name:    src
Committed By:   christos
Date:           Mon Feb 20 18:18:30 UTC 2012

Modified Files:
        src/sys/kern: kern_exec.c

Log Message:
Posix spawn fixes:
- split the file actions allocation and freeing into separate functions
- use pnbuf
- don't play games with pointers (partially freeing stuff etc), only check
  fa and sa and free as needed using the same code.
- use copyinstr properly
- KM_SLEEP allocation can't fail
- if path allocation failed midway, we would be possibily freeing
  userland strings.
- use sizeof(*var) instead sizeof(type)
