Hi all,
After merging the userns tree, today's linux-next build (x86_64
allmodconfig) failed like this:
In file included from include/linux/kernel.h:19,
from mm/debug.c:9:
mm/debug.c: In function 'dump_mm':
mm/debug.c:251:28: error: 'const struct mm_struct' has no member named 'core_state'
251 | mm->binfmt, mm->flags, mm->core_state,

mm/debug.c:208:2: note: in expansion of macro 'pr_emerg'

Caused by commit
483f2bb374b7 ("coredump: Limit coredumps to a single thread group")
I have used the userns tree from next-20211006 for today.
