Hi Linus, Please pull these execve updates for v6.2-rc1. Most are small refactorings and bug fixes, but three things stand out: switching timens (which got reverted before) looks solid now, FOLL_FORCE has been removed (no failures seen yet across several weeks in -next), and some whitespace cleanups (which are long overdue). The latter does end up conflicting with changes from Al[1], but should be trivial to resolve. Thanks! -Kees [1] https://lore.kernel.org/linux-next/20221128143704.3fe8f7b1@xxxxxxxxxxxxxxxx/ The following changes since commit 9abf2313adc1ca1b6180c508c25f22f9395cc780: Linux 6.1-rc1 (2022-10-16 15:36:24 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/execve-v6.2-rc1 for you to fetch changes up to 6a46bf558803dd2b959ca7435a5c143efe837217: binfmt_misc: fix shift-out-of-bounds in check_special_flags (2022-12-02 13:57:04 -0800) ---------------------------------------------------------------- execve updates for v6.2-rc1 - Add timens support (when switching mm).
