Eric Dumazet c12837d1bb ref_tracker: use __GFP_NOFAIL more carefully 
syzbot was able to trigger this warning from new_slab()
		/*
		 * All existing users of the __GFP_NOFAIL are blockable, so warn
		 * of any new users that actually require GFP_NOWAIT
		 */
		if (WARN_ON_ONCE(!can_direct_reclaim))
			goto fail;

Indeed, we should use __GFP_NOFAIL if direct reclaim is possible.

Hopefully in the future we will be able to use SLAB_NOFAILSLAB
option so that syzbot can benefit from full ref_tracker
even in the presence of memory fault injections.
