Both can be still found in the SCSI subsystem, but the typedefs have been moved to a single file, scsi_typedefs.h to make their future removal easier, for example: -"typedef struct scsi_host_template Scsi_Host_Template;" +"typedef struct scsi_cmnd Scsi_Cmnd;" Also, most C99 enhancements are encouraged to the extent they are supported by the relevant gcc compilers.
