when I'm reading data from a SCSI CDROM e.g. using
dd if=/dev/scd0 bs=2k of=/dev/null
the sync(2) system call is blocked until the "dd" command is terminated. why ? dd opens /dev/scd0 read-only; writing to a pipe gives the same problem so it's not writing to /dev/null...
using Linux-2.0.27, Toshiba CDROM drive connected to an AHA1542B (only device on this SCSI bus; SCSI disks connected to NCR810).
