A system under stress can experience failures during this allocation process resulting in a warning being issued. This message can be of concern to end users even though the failure is not fatal. Since the failure is not fatal and can occur multiple times, the driver should include the __GFP_NOWARN flag to suppress the warning message from being issued.
