Description of problem:
have /tmp as a jfs filesystem. On rare occasions, when the backups run, too many
resource forks are opened or some other magic condition, and /tmp justs stops
answering.

Processes using /tmp hang and are unkillable, /tmp can't be unmounted cleanly,
sometimes even fails a sysrq sync and unmount.

Version-Release number of selected component (if applicable):
kernel-2.4.20-20.7smp

How reproducible:
Always

Steps to Reproduce:
1.
2.
3.
cd to a jfs mount point, run this script:
#!/bin/bash

let LOOP0=0
let LOOP1=1
while /bin/true; do
  echo $LOOP0 ":" $LOOP1
  touch file$LOOP0$LOOP1
  mkdir dir$LOOP1$LOOP0
  let LOOP0+=1
  let LOOP1+=1
done

wait for the script to hang ... see if you can access that filesystem.

Actual Results:  ran it on /tmp. It hung, required a reboot. 



Expected Results:  when I reformatted /tmp as ext2, it died cleanly when it
couldn't create any more directories.
