Subject: mkfs.ext4: high default -i value undocumented

Hi,

Creating an ext4 filesystem on a 4 GB image file (to be loop-mounted 
later) gives me 256K inodes. Choosing -i 4096 instead gives 1M, which 
would mean the default for -i is 16384. Besides me finding 16384 a 
little unreasonable (XFS offers 2M inodes by default), the big 
point is that the mke2fs manpage (belonging to util-linux, hence Cc) 
does not mention this 16384 default.
Hope this can be addressed.

# rpm -q e2fsprogs util-linux
e2fsprogs-1.41.4-2.2
util-linux-2.14.2-2.2
