Subject: [ BUG ] acl sysfs entry remains after connection error

Hi!

I've found a bug in bluetooth stack.

I use bluetooth on ARM Linux machine to simultaneously send pictures
to 2 or 3 devices.
In a L2CAP connection stage (socket L2CAP 'connect') sometimes I get a
'Connection timeout error',
which is not a disaster because I can try to connect again. However
very often I get a kernel error,
which tells me that there is a duplicate entry in sysfs (acl...).

I've checked, and indeed acl connection entries are not removed from
sysfs after a connection fail.

How can I fix this?

PS. I've got latest 2.6.26 kernel.

Regards,
Marcin Undak

I've updated and after some tests problem seems to be fixed!

the latest kernel is 2.6.27-rc9. Please confirm that this problem still
exists.
