+Subject: fix sysvfs symlinks
+
+From: Al Viro <viro@zeniv.linux.org.uk>
+
+commit 0ebf7f10d67a70e120f365018f1c5fce9ddc567d upstream.
+
+The thing got broken back in 2002 - sysvfs does *not* have inline
+symlinks; even short ones have bodies stored in the first block
+of file.  sysv_symlink() handles that correctly; unfortunately,
+attempting to look an existing symlink up will end up confusing
+them for inline symlinks, and interpret the block number containing
+the body as the body itself.
+
+Nobody has noticed until now, which says something about the level
+of testing sysvfs gets ;-/
