Hi,
I am adding some code of my own **only** under
net/bluetooth in some file there.
There is only exactly one module which is changed by my addition,
This is net/bluetooth/bluetooth.ko
Now, when I run 'make -j2 modules' it takes quite a time, even If I
did one change in one line in a file under net/bluetooth.
I assume that it has to do with stage 2 of the build, which says something about
...
Building modules, stage 2.
MODPOST 855 modules
...
see below full log.
Now my question is this:
Is there a way to make things more efficent when building a module, on the
assumption that I do not change anything anywhere except /net/bluetooth (in this case)?
somehow telling the MODPOST that only one module is changes ?
I remember I once saw (not sure) a suggestion to build only a specified moule like:
make net/bluetooth
But in this case the result is the same.
any ideas?
