chattr: operation not supported ( on symlinks )

It seems that symlinks return -ENOTSUP for lsattr, causing chattr -R to spew errors. Why don't symlinks support attributes, and if not, shouldn't chattr know this and suppress operating on symlinks instead of spewing errors?

The VFS layer doesn't pass ioctl's down to the file system layer for symlinks. Thinking about this, arguably the right answer is to allow chattr to function on symlinks, since it cloud be useful to make symlinks immutable.
