Update.
1999-11-07 Andreas Jaeger <aj@suse.de> * sysdeps/unix/sysv/linux/scsi/scsi_ioctl.h: New file with some defines from Linux scsi_ioctl.h header. * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Added scsi_ioctl.h. * sysdeps/unix/sysv/linux/Dist: Likewise. * sysdeps/unix/sysv/linux/scsi/sg.h: Synced with Linux 2.3.26; pretty printed. * sysdeps/unix/sysv/linux/scsi/scsi.h (TYPE_ENCLOSURE): Added to sync with Linux 2.3.26.
