Take advantage of kmem_cache_zalloc(). Save a memset() call in
ext4_init_io_end() and save a few bytes.
Before:
[jj@dragon linux-2.6]$ size fs/ext4/page-io.o
text data bss dec hex filename
3016 0 624 3640 e38 fs/ext4/page-io.o
After:
[jj@dragon linux-2.6]$ size fs/ext4/page-io.o
text data bss dec hex filename
3000 0 624 3624 e28 fs/ext4/page-io.o
