oops I am sorry, actually it should be RFC I want to check whether I
need to cover more member under __KERNEL__
[RFC][PATCH] SCSI: userspace cannot use scsi_command_size_tbl, scsi_device_type and friends
userspace cannot use scsi_command_size_tbl and scsi_device_type defined in kernel
as well as its friends :
- SCSI_MAX_VARLEN_CDB_SIZE
- COMMAND_SIZE
- struct scsi_varlen_cdb_hdr
- scsi_varlen_cdb_length()
- scsi_command_size()
fix the following 'make headers_check' warnings:
usr/include/scsi/scsi.h:159: userspace cannot call function or variable defined in the kernel
usr/include/scsi/scsi.h:285: userspace cannot call function or variable defined in the kernel
