[lvm-devel] [PATCH 1/1] man: Fix lvcreate man page and clarify -L option

[Vivek Goyal]

Right now -L option does not say what's the difference between lower case
and upper case suffixes. They both are same. clarify that.

Right now man page says K represents kilobyte. That is 1000 bytes. But actually
code assumes it to be 1024 bytes. That is kibibytes. Clarify it.
