From 5584ea250ae44f929feb4c7bd3877d1c5edbf813 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Thu, 9 Feb 2017 14:39:57 +0100 Subject: xen: modify xenstore watch event interface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Today a Xenstore watch event is delivered via a callback function declared as: void (*callback)(struct xenbus_watch *, const char **vec, unsigned int len); As all watch events only ever come with two parameters (path and token) changing the prototype to: void (*callback)(struct xenbus_watch *, const char *path, const char *token); is the natural thing to do. Apply this change and adapt all users.
