Hi YAFFSer,

Do you remember the symlink problems that Nich have found
some time ago:

	> ln -s old new			# OK
	> rm new			# OK
	> ln -s old new			# ln say OK but ...
	> ls
	new: Not found			# ! entry is deleted
					# but the name still exist 
					# in the directory?
	> cd /
	> umount /yaffs; mount /yaffs	# umount may fail
	> cd yaffs
	> ls
	new

	# the problem is probably related with the dentry(ies)

I think that this problem was never solved because not reproductible.
Well, it happened again to me this afternoon!
The following patch seems to solve the problem:
(same as my old path proposal, same as done in yaffs_mknod,
 same/like done in ext2_symlink):

diff -ur yaffs-cvs/yaffs_fs.c yaffs/yaffs_fs.c

 		T((KERN_DEBUG"symlink created OK\n"));
 		return 0;
 	}

BTW, I think that the following patch (or some variant) is necessary:

PS. Apart this little problem YAFFS is working great!
Charles, thank you and succes with YAFFS2.
(Humm, I still need to convince my boss that we/I need a board
 with a 256Mb flash on it :-).
