| H A D | kfifo.h | diff 8a866fee3909c49738e1c4429a8d2b9bf27e015d Sun Oct 08 18:12:16 CEST 2017 Sean Young <sean@mess.org> kfifo: DECLARE_KIFO_PTR(fifo, u64) does not work on arm 32 bit
If you try to store u64 in a kfifo (or a struct with u64 members),
then the buf member of __STRUCT_KFIFO_PTR will cause 4 bytes
padding due to alignment (note that struct __kfifo is 20 bytes
on 32 bit).
That in turn causes the __is_kfifo_ptr() to fail, which is caught
by kfifo_alloc(), which now returns EINVAL.
So, ensure that __is_kfifo_ptr() compares to the right structure.
