[Pvfs2-developers] Problem with kernel module

I¹m one of the developers working with Walt here at Clemson.  We are running
some tests creating large numbers of files and I have run across what
appears to be a bug in the PVFS kernel module.  If I create 100,000 files
and the use the linux ls command, the output looks fine until it hits file
name 00034467.   Each file name listed after file 00034466 that has 2 or 3
entries.  The output of the pvfs2-ls command is correct with only a single
entry per file name.  It looks like we are hitting on some internal limit.
Here¹s an example of the ls output:

00034465
00034466
00034467
00034467
00034468
00034468
00034468
00034469
00034469
00034469
00034470
00034470
00034470
00034471
00034471
00034471
00034472
00034472
00034472
00034473

Any ideas what part of the kernel module code I should look at?  I¹m using
the 2.6 kernel.
