Subject: concurrent writes to xenbus device
Date: Thu, 26 May 2011 14:09:55 +0100 [thread overview]
Message-ID: <4DDE6D430200007800043AA4@vpn.id2.novell.com> (raw)
Is it supposed to be possible to write to the same struct file instance
from multiple threads/processes? Looking at xenbus_dev_write() I
can't see how such writes would be serialized, yet assuming that user
mode code always writes full messages it would seem consistent to
allow such.
Thanks, Jan
