From 8f05024cd3dbd3ec85923f3e8da05bf6db187d57 Mon Sep 17 00:00:00 2001 From: Sumit Saxena Date: Thu, 28 Jan 2016 21:04:27 +0530 Subject: megaraid_sas: Fastpath region lock bypass Firmware will fill out per-LD data to tell driver whether a particular LD supports region lock bypass. If yes, then driver will send non-FP LDIO to region lock bypass FIFO. With this change in driver, firmware will optimize certain code to improve performance.
