Hello Christoph,
Where does the '* 3' come from? I think that deserves a comment.
Additionally, this patch introduces a new warning when building with W=1:
block/scsi_ioctl.c:761:5: warning: no previous prototype for
‘scsi_cmd_buf_len’ [-Wmissing-prototypes]
Please consider adding #include <linux/blktrace_api.h> to the source
file in which scsi_cmd_buf_len() is added.
Thanks,
Bart.
