#     uapi: target: Replace fake flex-array with flexible-array member
#     
#     Zero-length arrays as fake flexible arrays are deprecated and we are
#     moving towards adopting C99 flexible-array members instead.
#     
#     Address the following warning found with GCC-13 and
#     -fstrict-flex-arrays=3 enabled:
#       CC      drivers/target/target_core_user.o
#     drivers/target/target_core_user.c: In function ‘queue_cmd_ring’:
#     drivers/target/target_core_user.c:1096:15: warning: array subscript 0 is outside array bounds of ‘struct iovec[0]’ [-Warray-bounds=]
#      1096 |         iov = &entry->req.iov[0];
#           |               ^~~~~~~~~~~~~~~~~~
#     In file included from drivers/target/target_core_user.c:31:
#     ./include/uapi/linux/target_core_user.h:122:38: note: while referencing ‘iov’
#       122 |                         struct iovec iov[0];
#           |                                      ^~~
#     
#     This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
#     routines on memcpy() and help us make progress towards globally
#     enabling -fstrict-flex-arrays=3 [1].
