[Amongst other things it is useful when I forget.] sg3_utils version 1.25 is work in progress; here is the ChangeLog to date: Changelog for sg3_utils-1.25 [20070728] - sg_sat_set_features: new utility (actually copied from examples directory); renamed examples version: sg__sat_set_features - sg_dd: add oflag=sparse to step over bs*bpt number of zeros; - with oflag=sparse, write last bs*bpt segment at end or after error so file length of OFILE is appropriate - when coe>1 then SCSI READ LONG logic remember extended block length of first encountered error - sg_dd, sgm_dd, sgp_dd: allow iflag=null and oflag=null both of which do nothing (placeholders) - sg_ses: sync with ses2r17 the r18 - sg_vpd: add block device characteristics VPD page - sg_logs: update background scan results log page, sbc3r11 - place source in subversion repository - convert build logic to use autotools (i.e. './configure ; make') - rename this file from CHANGELOG to ChangeLog - note: only utilities in main directory built by autotools infrastructure; subdirectories still use hand-crafted Makefiles Doug Gilbert - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
