+/// Standard SCSI support
-// PURPOSE
-// This is an interface routine meant to isolate the OS dependent
-// parts of the code, and to provide a debugging interface. Each
-// different port and OS needs to provide it's own interface. This
-// is the linux interface to the 3ware 3w-xxxx driver. It allows ATA
-// commands to be passed through the SCSI driver.
-// DETAILED DESCRIPTION OF ARGUMENTS
-// fd: is the file descriptor provided by open()
-// disknum is the disk number (0 to 15) in the RAID array
-// escalade_type indicates the type of controller type, and if scsi or char interface is used
-// command: defines the different operations.
-// select: additional input data if needed (which log, which type of
-// self-test).
-// data: location to write output data, if needed (512 bytes).
-// Note: not all commands use all arguments.
-// RETURN VALUES
-// -1 if the command failed
-// 0 if the command succeeded,
-// STATUS_CHECK routine:
-// -1 if the command failed
-// 0 if the command succeeded and disk SMART status is "OK"
-// 1 if the command succeeded and disk SMART status is "FAILING"

+// This is an interface routine meant to isolate the OS dependent

+// is the linux interface to the 3ware 3w-xxxx driver. It allows ATA
+// commands to be passed through the SCSI driver.
+// DETAILED DESCRIPTION OF ARGUMENTS
+// fd: is the file descriptor provided by open()
+// disknum is the disk number (0 to 15) in the RAID array
+// escalade_type indicates the type of controller type, and if scsi or char interface is used
+// command: defines the different operations.
+// select: additional input data if needed (which log, which type of
+// self-test).
+// data: location to write output data, if needed (512 bytes).
+// Note: not all commands use all arguments.
+// RETURN VALUES
+// -1 if the command failed
+// 0 if the command succeeded,
+// STATUS_CHECK routine:
+// -1 if the command failed
+// 0 if the command succeeded and disk SMART status is "OK"
+// 1 if the command succeeded and disk SMART status is "FAILING"
