write barrier and USB devices
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
[...]
