[PATCH] fix INIT_KFIFO in include/linux/kfifo.h - part 2

["David Härdeman" <david@hardeman.nu>]

DECLARE_KFIFO creates a union with a struct kfifo and a buffer array with
size [size + sizeof(struct kfifo)].

INIT_KFIFO then sets the buffer pointer in struct kfifo to point to the
beginning of the buffer array which means that the first call to kfifo_in
will overwrite members of the struct kfifo.

This patch was the least invasive fix I could come up with...
