[OpenAFS-devel] Are readdir() results in afs sorted?

[Martin MOKREJŠ]

Hi,
  while thinking which underlying filesystem to pickup for afs 
server partition, I came across ext2/3 email thread where is
suggested to take advantage of tune2fs -O dir_index /dev/xyz
using htrees, one needs first to do readdir(), then sort the
files by inode number before trying to open or stat them.

I'm curious if openafs would take advantage of that at all.
I don't expect one could use the preload library on server,
but still is worth of asking about it.

I have no idea if similar approach (I mean sort after readdir()) would help
also on other filesystems, like reiserfs and xfs. Any clues?
