   Add P_INEXEC flag to indicate that a process is currently exec'ing.

   Do not allow debugging of a process during exec.

MFS of procfs "kmem" cleanup. With the advent of an entirely

2001-08-13T19:45:41+00:00

sysctl-driven "ps" (and friends), special-casing of kmem gid in the
procfs authorization is no longer needed.  Clean up this morally
ambiguous code.  This MFC is from fs/procfs, as procfs has been
repo-copied.  Unlike -CURRENT, linprocfs required modification as
in -STABLE, it has direct knowledge of the inter-process debugging
authorization policy.  In -CURRENT, this is abstracted behind
p_cansignal().
