handling rdma apps using chroot

I'm looking for ideas on the best way for handling applications which use
chroot, which results in failures using the rdma libraries.  Specifically,
and not surprisingly, I see failures reading /sys/class/... and
/dev/infiniband/...

For background, I'm trying to run vsftpd over rsockets using the preload
library with fork support.  vsftpd will run only if I comment out its use of
chroot.  I can reproduce the issue by inserting a chroot call into rstream.

Does anyone have any suggestions?
