[PATCH 08/19] hpsa: choose number of reply queues more intelligently.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Stephen M. Cameron <scameron@xxxxxxxxxxxxxxxxxx>

No sense having 8 or 16 reply queues if you only have 4 cpus,
and likewise no sense limiting to 8 reply queues if you have
many more cpus.
