Subject: [PATCH] fuse: Don't check for file->private_data on open(). It is set by the core.
Date: Wed, 12 Nov 2014 19:56:21 +0100 [thread overview]
Message-ID: <1415818581-27476-1-git-send-email-martink@posteo.de> (raw)
In-Reply-To: <5463979C.6090600@gmail.com>
The miscdevice core now sets file->private_data to the struct miscdevice
so don't fail when this is not NULL.

sorry, I can't read ;) Is this a fix for your problem (instead of the first
patch)?
in case of fuse_ctl_add_conn(fc) failing things should proceed as before.
