lsscsi has been "CONFIG_SYSFS_DEPRECATED_V2" tolerant
since version 0.21 released 20080710. The current
version is 0.23 released 20091201 which will soon
be displaced by 0.24 to cope with the most recent
breakages.
Writing a user space tool that relies on sysfs structure
and contents, stable over the whole lk 2.6 series, is
impossible. For a history of my pain with lsscsi see
its ChangeLog.
Happily most of my tools are based on an ioctl! SG_IO
was a suggestion from Joerg Schilling and has now found
its way into most block devices. Now it has a new lease
of life in the bsg driver.
