Subject: [PATCH] libmultipath: create separate .so for unit tests
|
||
|
|
|
||
|
|
The unit tests use a lot of internal symbols that we don't want
|
||
|
|
to add to the ABI if we don't have to. As long as we don't
|
||
|
|
have to make incompatible changes to functions, we can work around
|
||
|
|
that by simply using a non-versioned library for the unit tests.
|
||
|
|
Therefore we add a seperate rule here. Do this before actually
|
||
|
|
adding a version script, to avoid breakage during bisection.
