Summary: - all printk(KERN_foo converted to pr_foo() - add pr_fmt and remove redundant prefixes - convert befs_() to va_format (based on patch by Joe Perches) - remove non standard %Lu - use __func__ for all debugging [akpm@linux-foundation.org: fix printk warnings, reported by Fengguang] Signed-off-by: Fabian Frederick <fabf@skynet.be> Cc: Joe Perches <joe@perches.com> Cc: Fengguang Wu <fengguang.wu@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
