[linux-lvm] [PATCH 29/35] lvresize: Specify --resize-fs-only when going to use fsadm resize

[Lukas Czerner <lczerner@redhat.com>]

When lvresize is calling fsadm to resize the file system, originally
it was the default action. However now fsadm support much more
features and it is doing the lvresize by itself. Luckily there is
still a way to tell fsadm to resize only the file system ane leave
the rest up to the lvresize - provide "--resize-fs-only" argument.

This commit adds "--resize-fs-only" argument when we are going to
use fsadm to resize the fs from within the lvresize.
