LinuxLists.cc - [PATCH RFC 2/2] kbuild: use interpreters to invoke scripts

2020-10-03 15:23:18

Subject: [PATCH RFC 2/2] kbuild: use interpreters to invoke scripts

We cannot rely on execute bits to be set on files in the repository.
The build script should use the explicit interpreter when invoking any
script from the repository.
