Subject: [PATCH 2/2] Do not run FS check as part of updating (re)size info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the FS tools tell us the minimum size of the file system we are supposed to
(see rhbz#1170803) consider that an evidence of the file system being in a good
enough shape to be resized.

Resolves: rhbz#1170803
