-Subject: [PATCH 175/454] drm/vc4: Fix false positive WARN() backtrace on
- refcount_inc() usage
-
-With CONFIG_REFCOUNT_FULL enabled, refcount_inc() complains when it's
-passed a refcount object that has its counter set to 0. In this driver,
-this is a valid use case since we want to increment ->usecnt only when
-the BO object starts to be used by real HW components and this is
-definitely not the case when the BO is created.
-
-Fix the problem by using refcount_inc_not_zero() instead of
-refcount_inc() and fallback to refcount_set(1) when
-refcount_inc_not_zero() returns false. Note that this 2-steps operation
-is not racy here because the whole section is protected by a mutex
-which guarantees that the counter does not change between the
-refcount_inc_not_zero() and refcount_set() calls.
-
-Fixes: b9f19259b84d ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl")
