2014-09-16megaraid_sas : MFI MPT linked list corruption fix[email protected]4-83/+241
Resending the patch. Addressed the review comments from Tomas Henzl. Added comment for to-do work. Problem statement: MFI link list in megaraid_sas driver is used from mfi-mpt pass-through commands. This list can be corrupted due to many possible race conditions in driver and eventually we may see kernel panic. One example - MFI frame is freed from calling process as driver send command via polling method and interrupt for that command comes after driver free mfi frame (actually even after some other context reuse the mfi frame). When driver receive MPT frame in ISR, driver will be using the index of MFI and access that MFI frame and finally in-used MFI frame’s list will be corrupted. High level description of new solution - Free MFI and MPT command from same context. Free both the command either from process (from where mfi-mpt pass-through was called) or from ISR context. Do not split freeing of MFI and MPT, because it creates the race condition which will do MFI/MPT list corruption. Renamed the cmd_pool_lock which is used in instance as well as fusion with below name. mfi_pool_lock and mpt_pool_lock to add more code readability.

2014-09-16megaraid_sas : Round down max sge supported by controller to power of two[email protected]1-2/+2
Resending the patch. Addressed the review comments from Tomas Henzl. Round down the max sge to power of two. Earlier max sge limit is 70 SGE, which will allow block layer to send 280K IO frame. It is optimal to provide max IO size aligned to the smallest possible stripe size. E.a Consider that we have configured RAID Volumes which does not allow Fast Path across the stripe. Raid volume with stripe size = 256K, will have peformance hit if we get io frame of size 280K. Driver will not send IO frame large than stripe size to the Fast Path. Also, FW will convert 280K frame into 256K + 24K. This is an additional overhead.

Resending the patch. Addressed the review comments from Tomas Henzl. Megaraid_sas driver can now work in host lock less mode. Remove host lock less as megaraid_sas driver will have safer access to raid map as described in earlier patch. We now keep Driver Raid map copy, which will make sure that driver will always have old or new map Driver raid map will be replaced safely in MR_PopulateDrvRaidMap(), so there is no issue even if IO is continue from the scsi mid layer. There is a plan to remove "host_lock" and "hba_lock" usage from megaraid_sas in future.
