Description of problem:
Enabling UdevNameAttr "DEVNAME" in plugin "disk" results in SElinux denied related to "tmpfs"

Version-Release number of selected component (if applicable):
collectd-5.9.0-5.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. install collectd

2. configure plugin "disk"
<Plugin disk>
       UdevNameAttr "DEVNAME"
</Plugin>

3. start collectd

Actual results:
tail -f /var/log/audit/audit.log | egrep "denied.*collectd"

per run many of such lines:

type=AVC msg=audit(1638874911.463:18520138): avc:  denied  { read } for  pid=1839851 comm="reader#0" name="b253:9" dev="tmpfs" ino=20061 scontext=system_u:system_r:collectd_t:s0 tcontext=system_u:object_r:udev_var_run_t:s0 tclass=file permissive=0


Expected results:
no SElinux denied entries

Additional info:

Tried to exclude "tmpfs" by

<Plugin disk>
        Disk "tmpfs"
        IgnoreSelected true
        UdevNameAttr "DEVNAME"
</Plugin>

but this won't help
