Exportfs and rpc.mountd optimalization

Exportfs and rpc.mountd optimalization

[Tomas Richter]

[-- Attachment #1: Type: text/plain, Size: 329 bytes --]

I did some optimalization of exportfs and rpc.mountd (linked
exportlist replaced by hash table). It has good results (I think) -
computing of exportfs and mountd (after running exportfs) is quicker.
Especially for long exportlists - about hundred thousand exports and
more.
Can someone look on it?
thanks

If you would like to propose changes to the nfs-utils package, then
please repost them in the form of a standard patch against the current
nfs-utils CVS tree (see http://sourceforge.net/projects/nfs) so that
they may be reviewed.

Cheers,
  Trond

It'd be interesting to see whether you could reproduce (and improve on)
Vincent Rouqueta's results:

Could you send your changes in the form of patches?  (See, e.g.,
http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt).
