This proposal is based on issues identified using the atomic_as_refcounter.cocci Coccinelle semantic patch script. Patch 1/2: proposes to convert the base implementation of variable count from atomic_t to refcount_t. This also includes the transition of atomic_*() API calls to their equivalent refcount_*() API calls. Patch 2/2: proposes to transition the atomic_*() API calls in i915 selftest use cases to their equivalent refcount_*() API calls. Please Note: 1. Patch 1/2 should be applied before patch 2/2 due to interdependency. 2. I did not enable to the selftest and debug configurations earlier while building the i915 base driver. With the build failures reported by the Kernel Test Robot, I have now included those changes. I did not find any other configurations that required additional atomic_* API call transition for this member variable of struct i915_active. Please let me know if there are other related disabled configurations that I should be enable for additional code coverage. 3. Any guidance on working with i915/selftests would be very helpful for my learning. Changes in v2: 1. Patch series introduced. 2. Handle build issues Reported-by: kernel test robot <lkp@...el.com> Earlier a standalone patch was sent for the i915 base driver only. The Kernel Test Robot reported failure for additional atomic_*() calls specific to i915 debugging support when enabled. This version now includes those changes as well. 3. Handle build issues Reported-by: kernel test robot <lkp@...el.com> for i915/selftests Include changes for i915/selftests use cases for atomic_* to refcount_* transition.
