# Merge: e2f0c565ec70 77f6ab8b7768
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Tue Nov 10 10:33:55 2020 -0800
# 
#     Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
#     
#     Pull core dump fix from Al Viro:
#      "Fix for multithreaded coredump playing fast and loose with getting
#       registers of secondary threads; if a secondary gets caught in the
#       middle of exit(2), the conditition it will be stopped in for dumper to
#       examine might be unusual enough for things to go wrong.
#     
#       Quite a few architectures are fine with that, but some are not."
#     
#     * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
#       don't dump the threads that had been already exiting when zapped.
