We now get the device number in the warning message : "EXT3-fs warning (device hda1): ext3_setup_super: maximal mount count reached, running e2fsck is recommended" It also adds the device information on a pair of printk(KERN_ERR) (this was first suggested by Kasper two weeks ago). It also adds the device information on the "mounted filesystem" message : "EXT3-fs: hda1 is now mounted with ordered data mode." It also replaces some whitespaces by tabs to increase consistency within super.c . One unused variable was removed in ext4/super.c . I will work on replacing all printks in ext3/ext4 in the coming days if no one / beats / already has beaten / me to it. Compile tested on ext4, compiled and booted on ext3, however not all string changes have been tested.
