[LTP] [RFC] [PATCH 0/2] io_uring READ(V), WRITE(v) operation tests

[Sachin Sant]

This patch series adds a set of test case to validate
IOURING READ & WRITE (io_uring03), READV & WRITEV (io_uring04)
operations. The patch also adds a common header file to
avoid code duplication.

These patches have been tested successfully on ppc64le
arch (fedora and SLES flavours)

Code is available
at https://github.com/sacsant/ltp/tree/uring_fio
