From 7826ca5d6aca691dcb6f98ab203a090d42e79337 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Fri, 3 Nov 2017 10:02:40 +0100 Subject: [PATCH] mount: add mount with ignore=1 for unsupported filesystems MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit So far a check for unsupported filesystem was in the mount_add_list which was simply stopping mount from being added to the global list. This resulted in mount_dev_add continuously not being able to find a mount for the given block device and trying to add it over and over. That was non-optimal becuse with unsupported filesystem present the code was checking all its parameters every second. Fix this by: 1) Moving check out of the mount_add_list to keep all logic in the caller function. 2) Adding mount with ignore=1 for unsupported filesystem instead of ignoring it.
