        src/sys/kern: vfs_lookup.c
Log Message:
Fix obscure bug in namei(), which was the cause of PR 7306.

The problem is that if "sl" is a symbolic link, a lookup on "sl/" will
be flagged as the last component. Thus VOP_LOOKUP will lock the parent
directory. But when lookup() exits, ni_pathlen will be greater than one,
as "/" is left in the name, and namei() would not unlock the parent. The
next call to lookup() to resolve the symbolic link would fail as the parent
was still locked.
