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

[Patrick Schreurs]

Hi Dave,

I think it's save to consider this issue fixed. We have currently 9 
servers operational with these patches and they have been stable so far. 
For a 100% certainty we'll have to test/wait a little bit longer, but 
considering the frequency of crashes we saw earlier i think it's save to 
come to a conclusion.

I hope these patches will be included in 2.6.33 and will be back ported 
to at least 2.6.32.

Many thanks to Dave and to Christoph for fixing this apparently rare and 
seldom triggered condition.

-Patrick
