Modified: sys/msdosfs msdosfs_vnops.c
Log:
Don't "remember" where the target directory slot is. The target
slot doesn't move. "Remembering" the target slot was a no-op for
files, but for directories it changed the target slot to slot of
the "." entry in the source directory. Thus rename("a", "b/c")
(where "a" is any directory and "b/c" is an empty directory) was
essentially
unlink("b/c"); rename("a/.", "a"); unlink("a");
where the middle rename corrupts "a/." and the final unlink detaches
"a" and everything underneath it from the directory tree although
not from the file system.
