From aa6a7a97803b1106d2200c889a2260f81059c450 Mon Sep 17 00:00:00 2001 From: Andreas Schneider Date: Thu, 27 Sep 2012 19:01:15 +0200 Subject: s3fs-smbd: Move housekeeping to the background process. If you add 200 printers using lpadmin. Then you wait for the printcap cache to expire. As soon as this expires we notify all deamons that they should reload the printers. This mean we need to create the default registry keys for each printer. If you do e.g. a 'smbclient -L' during that time you will get a lot of timeouts. This lets the housekeeping function of the printcap cache do the task of creating the default registry keys in background queue process. When it is done with the task it will tell all smbd childs to reload the printers and the 200 printers appear.
