Description

https://github.com/ceph/ceph/pull/5853

When specified pool is empty or doesn't contain valid bench objects, rados bench can crash because it attempts to memcmp through NULL pointer. Added check for valid object size (which also fixes the case when objects are there, but they're truncated), and made object_size being size_t instead of int.

Also, fix lock issue under similar conditions in seq_read_bench().
