[Yaffs-archive] YAFFS directory looping issue - report & fix

[Charles Manning]

Hi YAFFSers:

A problem that can happen under YAFFS direct and WinCE is that a directory 
can be renamed to be ints own decendent.

eg.

mkdir /a
mkdir /a/b
mv /a /a/b/c
Now the whole of /a is "lost"


The directory and all its dependents still exist, but cannot be accessed. 
Bummer.

This does not occur under Linux because the VFS knows to take care of us.

Both YAFFS direct and WinCE have been fixed. The YAFFS direct fix is being 
checked in right now but my network access to Aleph1 CVS is very slow right 
now and I hope it completes OK. [Just did]

The WInCE stuff will be checked in later this week with some error code fixes.
