[pve-devel] [PATCH v2 ct 0/9] mount hotplugging & new mount api

[Oguz Bektas]

a few issues , we talked with wolfgang off-list so he'll
send a v3.

* target directories are not created when hotplugging
* apparmor profile needs to be adapted
* missing case for hotplugging unused disks, they are currently
registered as a change and not a new mount, the code doesn't handle that
* nitpicks on function names :P
