Hi,
today I experienced double directory entries from a NFS mounted dir,
e.g. the file "file1.ext" is listed *twice* in the output.
The following under a 2.6.20 NFS client; Server was 2.6.18.8, NFS over UDP.
Mountpoint was not superblock-shared because it was a unique mount.
ls output:
drwxr-xr-x 3 user grp 296 Mar 15 17:28 ./
drwxr-xr-x 3 user grp 296 Mar 15 17:28 ./

d_type=DT_REG, d_reclen=40, d_name="00001.proc.pbs"}}, 32768) = 456
Only umounting and remounting did cure the problem which hasn't
reappeared as of now. The problem seemed to be localized into one
directory.
ATM I don't know how to track that down or supply any more information.
Please include me on CC.
Cheers,
