Btrfs: make sure new inode size is ok in fallocate
We have been failing xfstest 228 forever, because we don't check to make sure
the new inode size is acceptable as far as RLIMIT is concerned. Just check to
make sure it's ok to create a inode with this new size and error out if not.
With this patch we now pass 228.
