 Ouch. Watch it, if you are using 2.4.11

2.4.11 had a fix for a symlink DoS attack, but sadly that fix broke the
creation of files through a dangling symlink rather badly (it caused the
inode to be created in the very same inode as the symlink, with unhappy
end results).

Happily nobody uses that particular horror - or _almost_ nobody does. It
looks like at least the SuSE installer (yast2) does, which causes a nasty
unkillable inode as /dev/mouse if you use yast2 on 2.4.11.

("debugfs -w rootdev" + "rm /dev/mouse" will remove it, although I suspect
there are other less drastic methods too if your fsck doesn't seem to
notice anything wrong with it. Only one report of this actually happening
so far).

So I made a 2.4.12, and renamed away the sorry excuse for a kernel that
2.4.11 was.
