Subject: kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n
X-Git-Tag: for-6.11/block-post-20240722~6^2~2^2~2
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=8d1001f7bdd0553a796998f4fff07ee13e1c1cad;p=linux-2.6-block.git

kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n

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

To make it work irrespective of CONFIG_MODULES, this commit specifies
the directory path, /lib/modules/%{KERNELRELEASE}, instead of individual
files.

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.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.
