>Description:

While looking at an NTFS partition, a ls in a certain directory did not
show the first (sorted case-insensitively) few files or subdirectories
in that directory; nor does an 'echo *' print those first few entries.
An explicit 'ls entryname' does, however, see the file/subdirectory,
which can also be opened normally.  (The behavior is similar to that seen
when a directory's mode has the x bit set but not the r bit, but only
fir the first few entries; all the later entries are visible normally.)

This behavior was first seen when vnd-mounting a disk image under
4.0_STABLE; however, a NetBSD 5.0_BETA CD also had the same problem
reading from the actual drive in the machine the image had been taken
from.  A Windows XP CD, booted to the "Recovery Console" on that
machine, could see all the entries in that directory normally.

There are 7 subdirectories and 6 files not showing up, a total of 13
entries.  (Not all have been shown here, only a representative sample.)

Note that this doesn't seem to affect all directories - I've used NTFS
mounts before and this is the first place I've encountered it.

>Fix:
Not yet known.  Since it affects (at least) ls, shell wildcard
expansion, and shell path completion, it's not simply a problem in ls.
