Subject: [PATCH 16/33] generic/679: disable for fuse2fs

From: Darrick J. Wong <djwong@...nel.org>

fuse2fs' fallocate implementation follows xfs' behavior of failing an
fallocate up front if there isn't enough free space in the filesystem to
allocate @len bytes, even if most of the range is actually already
allocated.  This is an engineering decision on the part of the author
(me) not to support the corner case of preallocating a not very sparse
file because that would just be more code to maintain.
