Arnd Bergmann 3add1d93d9 nvme-fc: avoid gcc-10 zero-length-bounds warning ... When CONFIG_ARCH_NO_SG_CHAIN is set, op->sgl[0] cannot be dereferenced, as gcc-10 now points out: drivers/nvme/host/fc.c: In function 'nvme_fc_init_request': drivers/nvme/host/fc.c:1774:29: warning: array subscript 0 is outside the bounds of an interior zero-length array 'struct scatterlist[0]' [-Wzero-length-bounds] 1774 | op->op.fcp_req.first_sgl = &op->sgl[0]; | ^~~~~~~~~~~ drivers/nvme/host/fc.c:98:21: note: while referencing 'sgl' 98 | struct scatterlist sgl[NVME_INLINE_SG_CNT]; | ^~~ I don't know if this is a legitimate warning or a false-positive. If this is just a false alarm, the warning is easily suppressed by interpreting the array as a pointer.
