Merge tag 'for-linus-2020-01-03' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull thread fixes from Christian Brauner:
"Here are two fixes:
- Panic earlier when global init exits to generate useable coredumps.
Currently, when global init and all threads in its thread-group
have exited we panic via:
do_exit()
-> exit_notify()
-> forget_original_parent()
-> find_child_reaper()
This makes it hard to extract a useable coredump for global init
from a kernel crashdump because by the time we panic exit_mm() will
have already released global init's mm. We now panic slightly
earlier. This has been a problem in certain environments such as
Android.
- Fix a race in assigning and reading taskstats for thread-groups
with more than one thread.
This patch has been waiting for quite a while since people
disagreed on what the correct fix was at first"
