    Subject[PATCH v3 0/4] module: Merge same-name module load requests
    Date
    Changes since v2 [1]:
    - Add kselftests to verify the expected behavior.
    - Split a clean-up change to the module_mutex comment into a separate patch.
    - Clarify a description of the main patch and mention that it fixes also
    a recently reported problem with module vmap space allocation errors.
    - Improve some code comments.

    Changes since v1 [2]:
    - Change the error returned by a duplicate load when the main insert
    fails from -ENODEV to -EBUSY.
    - Change the error returned by a duplicate load when a same-name module
    is going from -EAGAIN to -EBUSY.
    - Use a per-shared_load_info completion object to inform waiting loads
    when the main one is done.
    - Add a patch to correct wake up of module_wq.
