write barrier and USB devices

[Martin Steigerwald <Martin@xxxxxxxxxxxx>]

Hello!

Does the usb mass storage driver support write barriers?

I think it does, since XFS doesn't complain:

---------------------------------------------------------------------
shambala:~> mount -o barrier /dev/sdb2 /mnt/daten
(note barrier is default since 2.6.17, but anyway)

shambala:~> tail -f /var/log/syslog
[...]

Mar 30 15:11:59 shambala kernel: Ending clean XFS mount for filesystem: 
sdb2
---------------------------------------------------------------------
