/**
* scsi_bios_ptable - return copy of block device's partition table
* @dev: pointer to block device
Each struct Scsi_Host instance has a spin_lock called struct
Scsi_Host::default_lock which is initialized in scsi_host_alloc() [found in
hosts.c]. Within the same function the struct Scsi_Host::host_lock pointer
-is initialized to point at default_lock with the scsi_assign_lock() function.
-Thereafter lock and unlock operations performed by the mid level use the
-struct Scsi_Host::host_lock pointer.
-
-LLDs can override the use of struct Scsi_Host::default_lock by
-using scsi_assign_lock(). The earliest opportunity to do this would
-be in the detect() function after it has invoked scsi_register(). It
-could be replaced by a coarser grain lock (e.g. per driver) or a
-lock of equal granularity (i.e. per host). Using finer grain locks
-(e.g. per SCSI device) may be possible by juggling locks in
-queuecommand().
+is initialized to point at default_lock. Thereafter lock and unlock
+operations performed by the mid level use the struct Scsi_Host::host_lock
+pointer. Previously drivers could override the host_lock pointer but
+this is not allowed anymore.
