I'm not the person above that said to "try to avoid", but I do have some
info regarding this.
It isn't that they won't work, just you *may* have issues with 4k
stacks. Here is one of the reasons: http://lkml.org/lkml/2004/7/20/62
. Basically there is a potential for a kernel oops if the XFS
filesystem gets *near* full and tries to free some reserved space.
There was another reason posted on the lkml, but I don't recall it nor
have a link handy (sorry).
That being said. XFS has been working great for me and I have no
intention of changing in the near term. Of course I still use 8K stacks
though (on 2.6.9-rc2).
