commit 23bcbc3512a6609216b6884a3bf088684d1e7c72
Author: Andrew Price <anprice@redhat.com>

gfs2_grow: Don't try to open an empty string
sdp->device_name wasn't getting set in gfs2_grow so is_gfs2() (called
via check_for_gfs2()) fails to open "" and so we get an ENOENT.
This fixes the open("") by setting sdp->device_name before passing it to
is_pathname_mounted(), which has been updated to make it more clear
which args will be modified by it.
is_gfs2() and check_for_gfs2() have also been removed from libgfs2 as
these were the only places they were being called and they aren't
needed: superblock checking is done further along via other functions
calling check_sb().

commit 25c6e51bb4d083eb341bbc8541bb2ad278988f10
Author: Andrew Price <anprice@redhat.com>
Date: Sat Nov 16 02:10:52 2013 -0600
libgfs2: Add lgfs2_open_mnt* functions
lgfs2_open_mnt is a replacement for is_pathname_mounted which tries to reduce
races by opening paths speculatively and passing back the open fds once they're
known to be correct. lgfs2_open_mnt_{dev,dir} build on this to provide a
convenient way to open just the device or mount directory relating to a path
which could be either.
