adam radford c1529fa25e [SCSI] megaraid_sas: Add fpRead/WriteCapable, fpRead/WriteAcrossStripe checks
The following patch for megaraid_sas fixes the fastpath code decision
logic to use fpRead/WriteCapable, fpRead/WriteAcrossStripe flags
instead of the old logic.  This fixes a bug where fastpath writes
could be sent to a read only LD.

Arnd Bergmann 5edc341313 drivers: remove extraneous includes of smp_lock.h
These were missed the last time I cleaned this up
globally, because of code moving around or new code
getting merged.
