Hello,

I tried running a kmemleak and DEBUG_SLUB enabled kernel, but almost
within 5 minutes of starting the backup process, I got:

[ 486.863124] kmemleak: Cannot allocate a kmemleak_object structure
[ 486.887195] kmemleak: Automatic memory scanning thread ended
[ 486.906604] kmemleak: Kernel memory leak detector disabled


Any ideas?

Thanks,
Dimitris
