[PATCH v2] kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n
Posted by Masahiro Yamada 1 year, 5 months ago 
When CONFIG_MODULES is disabled, 'make (bin)rpm-pkg' fails:

  $ make allnoconfig binrpm-pkg
    [ snip ]
  error: File not found: .../linux/rpmbuild/BUILDROOT/kernel-6.10.0_rc3-1.i386/lib/modules/6.10.0-rc3/kernel
  error: File not found: .../linux/rpmbuild/BUILDROOT/kernel-6.10.0_rc3-1.i386/lib/modules/6.10.0-rc3/modules.order

Specify the directory path, /lib/modules/%{KERNELRELEASE}, instead of
individual files to make it work irrespective of CONFIG_MODULES.

However, doing so would cause new warnings:

  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.alias
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.alias.bin
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.builtin.alias.bin
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.builtin.bin
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.dep
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.dep.bin
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.devname
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.softdep
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.symbols
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.symbols.bin

These files exist in /lib/modules/%{KERNELRELEASE} and are also explicitly
marked as %ghost.

Suppress depmod because depmod-generated files are not packaged.

Fixes: 615b3a3d2d41 ("kbuild: rpm-pkg: do not include depmod-generated files")
