kernel/linux.git/scripts/check-function-names.sh, branch v6.19.11Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.19.112026-01-14T13:13:41+00:00kbuild: prefer ${NM} in check-function-names.sh2026-01-14T13:13:41+00:00Carlos Llamascmllamas@google.com2025-12-18T17:58:06+00:00urn:sha1:946d462346d2ded161cfd3dc62a61d7050d9f9ec
The check-function-names.sh scripts invokes 'nm' directly and this can
be problematic during cross-compilation when the toolchain is different
from the system's default (e.g. LLVM=1).
scripts/check-function-names.sh: nm: not found
Let's prefer the ${NM} variable which is already set by kbuild. However,
still fallback to plain 'nm' to ensure the script is still usable when
called directly.

Commit 9c7dc1dd897a ("objtool: Warn on functions with ambiguous
-ffunction-sections section names") only works for drivers which are
compiled on architectures supported by objtool.
Make a script to perform the same check for all architectures.
