+autofs-5.0.7 - don't schedule new alarms after readmap
+
+From: Leonardo Chiquitto <leonardo.lists@gmail.com>
+
+Currently, a new alarm is scheduled every time the daemon receives
+a SIGHUP (map re-read) or SIGUSR1 (forced expiration). Besides that,
+map re-reads started on demand when a map is found to be outdated
+also generate a new alarm.
+
+Once added, these alarms are never deleted and hence increase the
+number of times the daemon wakes up to run the expiration procedure.
+After a couple of months, in setups with many mount points, it's
+normal to see automount waking up every second to handle the
+expiration timer.
+
+This patch removes the alarm scheduling from the readmap cleanup
+routine and makes sure the alarm is re-added after the expiration
+process only when it was not triggered by SIGUSR1.
+
+I couldn't think of any use case to justify keeping these alarms:
+it's critical to have the alarm ticking every timeout/4 seconds,
+but more than one periodic alarm running doesn't seem to make
+sense.
