You could try the VFS lock patch for 2.4.11 on 2.4.17. If you upgrade to 2.4.18
then get the VFS lock patch from

http://tech.sistina.com/cgi-bin/cvsweb.cgi/~checkout~/LVM/PATCHES/linux-2.4.18-VFS-lock.patch?rev=1.1

rather than the 1.0.4 release.

However, I think 2.4.19rc1 might be a better kernel (it's what I'm running - I
went from 2.4.17), the VFS lock patch for that kernel is at
