I don't think so. IIRC that was a genuine difference where double entries
ended up in the list.

Hmmm...
The inodes are the same and the data is the same. This means that one of three
things is happening:
1) Somehow during the scan, two identical object headers are read and the
there are genuine double entries within yaffs_guts directory lists.
-or-
2) The directory reading process (in yaffs_fs.c) is feeding back the same
entry twice.
-or-
3) Your shell is reporting it twice.
There are some subtle interaction issues between the shell and the directory
reading mechanism that can result in double reporting.
Questions:
1) Can you plz do # ls -ial that gives a bit more info.
2) What does the /proc/yaffs look like?
3) Turn on some tracing, in particular YAFFS_TRACE_OS to trace out
yaffs_readdir.
4) What shell are you using?
5) What happens if you do something like mv? Do both entries move, just one,
or does the problem get fixed?
