["Andrew Doran" <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Sat Jan 25 15:41:52 UTC 2020

Modified Files:
        src/lib/libpthread: pthread.c
        src/sys/compat/netbsd32: netbsd32_lwp.c
        src/sys/kern: sys_lwp.c
        src/sys/sys: lwp.h

Log Message:
- Fix a race between the kernel and libpthread, where a new thread can start
  life without its self->pt_lid being filled in.

- Fix an error path in _lwp_create().  If the new LID can't be copied out,
  then get rid of the new LWP (i.e. either succeed or fail, not both).

- Mark l_dopreempt and l_nopreempt volatile in struct lwp.
