[Qemu-devel] [PATCH v2] block/iscsi.c: Fix printf format error.

[Qemu-devel] [PATCH v2] block/iscsi.c: Fix printf format error.

[Richard W.M. Jones]

From: "Richard W.M. Jones" <rjones@redhat.com>

The error on armv7hl was:

block/iscsi.c: In function ‘is_request_lun_aligned’:
block/iscsi.c:251:26: error: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘int64_t’ [-Werror=format=]
                          iscsilun->block_size, sector_num, nb_sectors);
                          ^

This also splits the long line to comply with qemu coding guidelines.

Tab-damaged now. ;) scripts/checkpatch.pl complains about both issues -
can be used as commit hook for convenience.

Cheers,
