Currently 'make C=1 fs/io_uring.o' generates sparse warning:
CHECK fs/io_uring.c
fs/io_uring.c: note: in included file (through
include/trace/trace_events.h, include/trace/define_trace.h, i
nclude/trace/events/io_uring.h):
./include/trace/events/io_uring.h:488:1:
warning: incorrect type in assignment (different base types)
expected unsigned int [usertype] op_flags
got restricted __kernel_rwf_t const [usertype] rw_flags
This happen on cast of sqe->rw_flags which is defined as __kernel_rwf_t,
this type is bitwise and requires __force attribute for any casts.
However rw_flags is a member of the union, and its access can be safely
replaced by using of its neighbours, so let's use poll32_events to fix
the sparse warning.
