Call scnprintf() instead of snprintf() since the latter may return an incorrect count in cases where the write is truncated to fit. scnprintf() returns the count of what was actually written; snprintf() returns the count of what would have been written. Signed-off-by:

When using a virtual SCSI disk in a VMWare VM if blkdev_issue_zeroout is used data can be improperly zeroed out using the mptfusion driver. This patch disables write_same for this driver and the vmware subsystem_vendor which ensures that manual zeroing out is used instead.

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. Signed-off-by:

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. Signed-off-by:
