Subject: [PATCH v2] Unify log messages in ext3
make messages produced by ext3 more unified. It should be
easy to parse.

[ 4893.684892] reservations ON
[ 4893.684896] xip option not supported
[ 4893.684964] EXT3-fs warning: maximal mount count reached, running
e2fsck is recommended
dmesg after patch:
[ 873.300792] EXT3-fs (loop0): using internal journaln
[ 873.300796] EXT3-fs (loop0): mounted filesystem with writeback data mode
[ 924.163657] EXT3-fs (loop0): error: can't find ext3 filesystem on dev loop0.
[ 723.755642] EXT3-fs (loop0): error: bad blocksize 8192
[ 357.874687] EXT3-fs (loop0): error: no journal found. mounting ext3 over ext2?
[ 873.300764] EXT3-fs (loop0): warning: maximal mount count reached, running e2fsck is recommended
