2003-06-25Avoid a divide by zero byKenneth R Westerback
1) Ensuring that both sd_scsi.c and sd_atapi.c report a device as offline when its disksize cannot be determined. 2) Ensuring blksize is always non-zero, with a default value of 512. 3) Eliminating a couple of unneeded 'sectors' variables, which makes the code easier for me to read if nothing else. The bug was introduced when sd_atapi.c was changed to allow 'incomplete' implementations to be reported as online. REALLY incomplete implementations (i.e. not even the disksize can be determined) would be reported online with a blksize of zero. Also fix a couple of knf nits in Mickey's last commit, and add another check for an rpm of 0. ok (pre-Mickey diffs) tdeval@ marc@ frantzen@
