#     Merge tag 'kbuild-gnu11-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild update for C11 language base from Masahiro Yamada:
#      "Kbuild -std=gnu11 updates for v5.18
#     
#       Linus pointed out the benefits of C99 some years ago, especially
#       variable declarations in loops [1]. At that time, we were not ready
#       for the migration due to old compilers.
#     
#       Recently, Jakob Koschel reported a bug in list_for_each_entry(), which
#       leaks the invalid pointer out of the loop [2]. In the discussion, we
#       agreed that the time had come. Now that GCC 5.1 is the minimum
#       compiler version, there is nothing to prevent us from going to
#       -std=gnu99, or even straight to -std=gnu11.
#     
#       Discussions for a better list iterator implementation are ongoing, but
#       this patch set must land first"
