[PATCH v5 0/3] drm/xe/xe_vm: Add error injection support to lock and prep

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

Error injection should use the error injection interface, and should be
decoupled from CONFIG_DRM_XE_DEBUG.  Remove TEST_VM_OPS_ERROR from the
code, and add error injection support to the function
vm_bind_ioctl_ops_lock_and_prep.  This necessitates marking the function
as noinline.

v2: Only noinline vm_bind_ioctl_ops_lock_and_prep when function error
injection is enabled (Brost)

v3: Add error_injectable function attribute (Brost, Harrison)

v4: Modify where error_injectable is defined and used (Brost, Michal)

v5: Update error_injectable descriptions (Michal)

Jonathan Cavitt (3):
  drm/xe: Add error_injectable define
  Revert "drm/xe: Add VM bind IOCTL error injection"
  drm/xe/xe_vm: Add error injection support to lock and prep
