15f08c3bdfSopenharmony_ci#       -O Use O_DIRECT (not available in 2.4 kernels),
16f08c3bdfSopenharmony_ci#       -S Use O_SYNC for writes
17f08c3bdfSopenharmony_ci#       -o add an operation to the list: write=0, read=1,

19f08c3bdfSopenharmony_ci#          repeat -o to specify multiple ops: -o 0 -o 1 etc.
