scsi: nvme-fc: Add new routine nvme_fc_io_getuuid()

2022-05-20T00:24:56Z

Add nvme_fc_io_getuuid() to the nvme-fc transport. The routine is invoked by the FC LLDD on a per-I/O request basis. The routine translates from the FC-specific request structure to the bio and the cgroup structure in order to obtain the FC appid stored in the cgroup structure. If a value is not set or a bio is not found, a NULL appid (aka uuid) will be returned to the LLDD.
