[Intel-gfx] [PATCH v2 07/11] lib/ref_tracker: remove warnings in case of allocation failure

[Andrzej Hajda]

Library can handle allocation failures. To avoid allocation warnings
__GFP_NOWARN has been added everywhere. Moreover GFP_ATOMIC has been
replaced with GFP_NOWAIT in case of stack allocation on tracker free
call.
