I have found a bug in NFSv2.

[root@igor /tmp]# mount igor:/u u
[root@igor /tmp]# cd u
[root@igor u]# umask 000
[root@igor u]# ls -l q
ls: q: File o directory inesistente
[root@igor u]# touch q
[root@igor u]# ls -l q
-rw-r--r--    1 root     root            0 lug 13 07:56 q

This seems to be caused by use of unitialized current->fs->umask via
vfs_create called by nfsd_create.

Patch for 2.4.6 follows.
