Hi all,
(please Cc)
I just changed my kernel config slightly to activate some DEPRECATED
configs and alas, the change was interesting, suddenly there
was no /dev/sda shown anymore.
Userspace remain completely the same (debian/sid up2date).
The only changes I made in the .config file was:
-# CONFIG_SYSFS_DEPRECATED is not set
+CONFIG_SYSFS_DEPRECATED=y
+CONFIG_SYSFS_DEPRECATED_V2=y
-CONFIG_NFSD_DEPRECATED=y
+# CONFIG_NFSD_DEPRECATED is not set
and this made the /dev/sda* entries disappear.
Is that to be expected?
Best wishes
Norbert

Yes. Newer tools are incompatible with these settings, as noted in the
Kconfig help for these entries:
config SYSFS_DEPRECATED
...
Recent distributions and userspace tools after 2009/2010 depend on
the existence of /sys/class/block/, and will not work with this
option enabled.
SYSFS_DEPRECATED_V2 just forces this behaviour on.

Ouch, sorry, yes... didn't read that. I read only the short desc and hoped
that it might fix the input layer problem introduced in 2.6.37-rc, not
giving me brightness events.
Thanks.
Best wishes
