kernel/linux.git/scripts/Makefile.kstack_erase, branch v6.19.11Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.19.112025-07-30T00:17:46+00:00kstack_erase: Fix missed export of renamed KSTACK_ERASE_CFLAGS2025-07-30T00:17:46+00:00Kees Cookkees@kernel.org2025-07-29T23:50:48+00:00urn:sha1:fc525d625a22c2179877955ee87e33f532b0674c
Certain targets disable kstack_erase by filtering out KSTACK_ERASE_CFLAGS
rather than adding DISABLE_KSTACK_ERASE. The renaming to kstack_erase
missed the CFLAGS export, which broke those build targets (e.g. x86
vdso32).

In preparation for Clang stack depth tracking for KSTACK_ERASE,
split the stackleak-specific cflags out of GCC_PLUGINS_CFLAGS into
KSTACK_ERASE_CFLAGS.
