Hi, I've noticed that after loading the target core there's a message in syslog "Rounding down aligned max_sectors from 4294967295 to 4294967288" but without a prefix, printed from drivers/target/target_core_device.c. It's pr_info so the prefix should be defined at the top of the file as pr_fmt and it'll be picked by the pr_* macros automatically. I'm not sending a patch as I don't know what would be the preferred prefix, eg. drivers/target/target_core_user.c prints "tcmu daemon" but does not use pr_*, and there are several bare printk calls in the same file. This should be unified in some way but I'm not familiar with the target code. d.
