[PATCH 4/6] drm/amdkfd: Separate mqd allocation and initialization
Zeng, Oak
Oak.Zeng at amd.com
Tue Jun 4 02:52:47 UTC 2019
Introduce a new mqd allocation interface and split the original
init_mqd function into two functions: allocate_mqd and init_mqd.
This is preparation work to fix a circular lock dependency.
