183 It may be useful for a LLD to keep track of struct Scsi_Host instances
185 by the mid-level.  struct Scsi_Host instances are freed from
306 The Scsi_Host structure has had reference counting infrastructure added.
307 This effectively spreads the ownership of struct Scsi_Host instances
314 struct Scsi_Host:
316         Scsi_Host which has its reference count ^^ set to 1
332 ^^ struct Scsi_Host actually has 2 reference counts which are manipulated
375    scsi_host_get - increments Scsi_Host instance's refcount
376    scsi_host_put - decrements Scsi_Host instance's refcount (free if 0)

1193 struct Scsi_Host
1195 There is one struct Scsi_Host instance per host (HBA) that an LLD
1196 controls. The struct Scsi_Host structure has many members in common
1197 with "struct scsi_host_template". When a new struct Scsi_Host instance
1226                    this struct Scsi_Host instance was spawned
1230     sh_list      - a double linked list of pointers to all struct Scsi_Host
1234     hostdata[0]  - area reserved for LLD at end of struct Scsi_Host. Size
1238                    the LLD for the Scsi_Host.  Used most often in validating
1257 scsi_change_queue_depth() (or struct Scsi_Host::cmd_per_lun). There will
1331 Each struct Scsi_Host instance has a spin_lock called struct 
1332 Scsi_Host::default_lock which is initialized in scsi_host_alloc() [found in 
1333 hosts.c]. Within the same function the struct Scsi_Host::host_lock pointer
1335 operations performed by the mid level use the struct Scsi_Host::host_lock
1367 relevant to LLDs is struct Scsi_Host::host_lock and there is
