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 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
