Previous version was sg3_utils001012. Arbitrarily start at package version 0.90 . Start Changelog. - incorporate Kurt Garloff's patches from Suse scsi.spm source rpm compilation: - add Kurt Garloff's sg_test_rwbuf utility to read and write to disk buffer - clean up Makefile to include a "make install" (and also add a "make uninstall"). - add "-uno" switch to sginfo - make raw and sg devices equally acceptable to sg_dd and sgp_dd. [Raw devices still not as fast as sg devices doing disk to disk copies in sgp_dd but this may be improved soon. Still faster than using dd!] - change lseek() in sg_dd and sgp_dd to _llseek() [using code borrowed from fdisk] so big disks can be properly offset with 'skip' and 'seek' arguments. [This change is significant for raw devices and normal files since sg devices already use 31 bit block addressing.] - rename sg_s3_inq to sg_inq. This utility allows the INQUIRY response to be decoded as per SCSI 3 and 4. Also can probe EVPD and CmdDt pages. - change multiplier suffixes on sg_dd, sgp_dd and sg_turs so lower case "k, m, g" are powers of 2 while "K, M, G" are powers of 10. This idea borrowed from lmdd (lmbench suite) - retire a few more less used utilities into the archive directory. - add man pages for sg_dd, sgp_dd and sg_map
