Hi Luis,
Sorry for late.

When using a directory with 'max_bytes' quota as a base for a mount,
statfs shall use that 'max_bytes' value as the total disk size. That
value shall be used even when using subdirectory as base for the mount.
A bug was found where, when this subdirectory also had a 'max_files'
quota, the real filesystem size would be returned instead of the parent
'max_bytes' quota value. This test case verifies this bug is fixed.

Finally, I've managed to come back to this test. The major changes since
v1 are:
- creation of an helper for getting total mount space using 'df'
- now the test sends quota size to stdout

For the 'SCRATCH_DEV' here, if you do:
SCRATCH_DEV="$SCRATCH_DEV/quota-dir"
twice, won't it be "${ceph_scratch_dev}/quota-dir/quota-dir" at last ?
Shouldn't it be:
SCRATCH_DEV="$TEST_DIR/quota-dir" ?
