Re: [dm-devel] [PATCH 0/7] some shared snapshot readability improvements

[Mikulas Patocka <mpatocka redhat com>]

Hi

Is it needed to just rename variables?

It doesn't add readability, the new variable names are no more readable 
than the old ones --- chaning "s" and "p" to "ps" and "dm" to "s" doesn't 
seem to make anything but confusion.
