This tells fio to not try to use POSIX calls on
"files" specified for an SPDK engine.
Note that w/o DISKLESSIO option set, fio would
figure out that "*" wasn't a real file. With this
option set, we now need to explicitly set its
real_file_size to 0 to tell fio to ignore it.
Found by Karol Latecki - he noticed that when
specifying lvols in the form "lvs/lvol" that
fio would create an empty "lvs" directory. Adding
this flag prevents things like this from happening.
