Analyzing fcoe with sparse currently fails. This is because struct fcoe_rcv_info contains two enum members that have been declared with __attribute__((packed)). Apparently gcc honors this attribute while sparse ignores it. The result is that sizeof(struct fcoe_rcv_info) == sizeof(struct sk_buff::cb) == 48 on a 64-bit system according to gcc, but not according to sparse. The patch below modifies the definition of struct fcoe_rcv_info such that gcc and sparse interpret this structure definition in the same way. The current sparse output is as follows: $ cd linux-2.6.34 $ make C=2 M=drivers/scsi/fcoe modules CHECK drivers/scsi/fcoe/fcoe.c include/scsi/fc_frame.h:81:9: error: invalid bitfield width, -1.
