RDS/IB tries to refill the recv buffer in softirq context using GFP_NOWAIT flag. However alloc failure is handled by queueing a work to refill the recv buffer with GFP_KERNEL flag. This means failure to allocate with GFP_NOWAIT isn't fatal. Do not print the PAF warnings if softirq context fails to refill the recv buffer. We will see the PAF warnings when worker also fails to allocate.
