This looks great. Like I said earlier, I did not find Brian Foster's

   xfs: check for stale inode before acquiring iflock on push

Thatnks for looking over this, Mark.

The above patch does not directly apply to the 3.0.x branch because
the rework of the log item lock/push logic in the AIL was not
included in the series. Hence I'm not sure that backportingthis
patch is necessary because the problem only arose after we change
the locking/push logic...

Cheers,

Dave.

Hi Dave.

The original problem was in Linux 2.6.X.

The patch in the above link is a 3.0.42 port of Brian's top of tree
patch. This version places the tests in AIL trylock routine. We have
been using it on Linux 3.0.x for a couple months and it has avoided
the hangs that we used to get before.

Thank-you again for the work.
