[PATCH] Inode reclaim fixes (was Re: 2.6.31 xfs_fs_destroy_inode: cannot reclaim)

[Patrick Schreurs]

Hello Dave,

I'm afraid we had another crash a few days ago. Have a look at the 
screenshot. Can you make anything out of it? This server is running 
2.6.32.3 with your inode-reclaim patch applied and XFS_DEBUG still enabled.

Thanks for looking into this.

-Patrick
