Re: [libvirt] [PATCH 4/7] Copy struct inotify_event entries to avoid alignment problems

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When reading the inotify FD, we get back a sequence of struct inotify_event, each with variable length data following. It is not safe to simply cast from the char *buf to the struct inotify_event struct since this may violate data alignment rules. Thus we must copy from the char *buf into the struct inotify_event instance before accessing the data. uml/uml_driver.c: In function 'umlInotifyEvent': uml/uml_driver.c:327:13: warning: cast increases required alignment of target type [-Wcast-align] e = (struct inotify_event *)tmp; Signed-off-by: Daniel P.
