Subject: [PATCH] modprobe: ignore builtin module on recursive removing
|
|
|
c49cfb |
|
|
|
c49cfb |
If there are built-in dependencies and any of them is built-in in
|
|
|
c49cfb |
the kernel, modprobe -r fails with
|
|
|
c49cfb |
|
|
|
c49cfb |
modprobe: FATAL: Module module_name is builtin.
|
|
|
c49cfb |
|
|
|
c49cfb |
It makes sense to ignore such dependencies for the case when
|
|
|
c49cfb |
removing is called for non-top level module.
|
|
|
c49cfb |
|
|
|
c49cfb |
Example: cifs module, it declares bunch of softdeps and the first
|
|
|
c49cfb |
one fails on some kernel configs:
|
|
|
c49cfb |
|
|
|
c49cfb |
modprobe: FATAL: Module gcm is builtin.
