CVS commit: src/sys

["Jason R Thorpe" <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej
Date:           Wed Apr 29 01:52:26 UTC 2020

Modified Files:
        src/sys/kern: kern_lwp.c kern_proc.c
        src/sys/sys: lwp.h proc.h

Log Message:
- proc_find() retains traditional semantics of requiring the canonical
  PID to look up a proc.  Add a separate proc_find_lwpid() to look up a
  proc by the ID of any of its LWPs.
- Add proc_find_lwp_acquire_proc(), which enables looking up the LWP
  *and* a proc given the ID of any LWP.  Returns with the proc::p_lock
  held.
- Rewrite lwp_find2() in terms of proc_find_lwp_acquire_proc(), and add
  allow the proc to be wildcarded, rather than just curproc or specific
  proc.
- lwp_find2() now subsumes the original intent of lwp_getref_lwpid(), but
  in a much nicer way, so garbage-collect the remnants of that recently
  added mechanism.
