[PATCH 0/3] debugfs: fixes to "file removal race" series

[Nicolai Stange <nicstange@gmail.com>]

Hi Greg,

the recent report by Sasha Levin made me review my debugfs
"file removal race" series again.

For your reference, the original series in question was posted here:
http://lkml.kernel.org/g/1458652280-19785-1-git-send-email-nicstange@gmail.com
It has been merged through your driver-core tree into mainline.


Unfortunately, I found three issues:

The first one is a minor code style issue.
The second one is more serious: on ->open() failure, references to modules
as well as memory are leaked.
The third one is a potential leak of module references with future debugfs
users.

The patches don't depend on each other and are unrelated except that they
all address issues introduced by the same series.
I tested them with linux-next 20160523.

Apologies and thanks,

Nicolai
