--- Comment #1 from Jan Kara (jack@...e.cz) ---
Yes, this is a design limitation of ext4. In principle, on disk format of a
symlink could be extended to allow for larger symlinks but that would require
an incompatible on-disk format change and someone determined enough to
implement all this in the kernel, e2fsck, libext2fs, etc. Also the motivation
for the work is decreased by the fact that commonly deployed filesystems with
4k block size do not exhibit the problem. So I personally don't think fixing
this is worth the effort.
