zfs-linux/0.6.5.6-0ubuntu29 ADT test failure with linux-snapdragon/4.4.0-1154.164

[Kelsey Steele]

This is a scripted bug report about ADT failures while running zfs-linux tests for linux-snapdragon/4.4.0-1154.164 on xenial. Whether this is caused by the dep8 tests of the tested source or the kernel has yet to be determined.

Testing failed on:

[Colin Ian King (colin-king)]

The snapdragon does not have ZFS built into the kernel, the system has limited memory and a slow backing store, so ZFS is not practical on this platform. The test should be avoided on this.

Ah, that makes sense. Thank you for the explanation Colin. I'll get this hinted for ADT
