When accidentally passing twice the same tag to qemu, kmemleak ended up
reporting a memory leak in virtiofs. Also, looking at the log I saw the
following error (that's when I realised the duplicated tag):
virtiofs: probe of virtio5 failed with error -17
Here's the kmemleak log for reference:
unreferenced object 0xffff888103d47800 (size 1024):
