2017-01-27block: split scsi_request out of struct requestChristoph Hellwig
And require all drivers that want to support BLOCK_PC to allocate it as the first thing of their private data. To support this the legacy IDE and BSG code is switched to set cmd_size on their queues to let the block layer allocate the additional space.

fc_bsg_jobdone() and bsg_job_done() are 1:1 copies now so use the bsg-lib one instead of the FC private implementation.

2016-11-17scsi: fc: Export fc_bsg_jobdone and use it in FC driversJohannes Thumshirn
Export fc_bsg_jobdone so drivers can use it directly instead of doing the round-trip via struct fc_bsg_job::job_done() and use it in the LLDDs. That way we can also unify the interfaces of fc_bsg_jobdone and bsg_job_done. As we've converted all LLDDs over to use fc_bsg_jobdone() directly, we can remove the function pointer from struct fc_bsg_job as well.
