Revision b71871395cf3a0ca7c0a7d79b4faa584ac872809 authored by Linus Torvalds on 23 March 2024, 15:43:21 UTC, committed by Linus Torvalds on 23 March 2024, 15:43:21 UTC
Pull more hardening updates from Kees Cook:

 - CONFIG_MEMCPY_SLOW_KUNIT_TEST is no longer needed (Guenter Roeck)

 - Fix needless UTF-8 character in arch/Kconfig (Liu Song)

 - Improve __counted_by warning message in LKDTM (Nathan Chancellor)

 - Refactor DEFINE_FLEX() for default use of __counted_by

 - Disable signed integer overflow sanitizer on GCC < 8
