OK, thanks.

btw, I have some directory readahead rework queued for 2.6.17
(ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16-rc6/2.6.16-rc6-mm1/broken-out/ext3_readdir-use-generic-readahead.patch).

That's non-htree-only.  Is there any sane way of doing htree directory
readahead?
