With
$ grep -e UBIFS_FS_DEBUG -e DYNAMIC_DEBUG .config
# CONFIG_UBIFS_FS_DEBUG is not set
CONFIG_DYNAMIC_DEBUG=y
Debug messages are kept in the object files due to the
dynamic_pr_debug() macro, even if they are never going to be printed:
$ make fs/ubifs/super.o
$ strings fs/ubifs/super.o | grep 'compiled on'
compiled on: Aug 11 2011 at 12:21:38
Use plain printk to fix this.

There is a similar issue in UBI - just fixed it. I'll send this to Linus
soon, as this is a regression (blown-up binaries even though debugging
is disabled).
