Heiko> Hello Roland, does OpenIB 1.0 RC2 (RC3, ...) still uses
    Heiko> libsysfs or is it only change for subversion head (trunk)?
All versions of libibverbs still use libsysfs.  However this patch for
libehca reduces the dependency on libsysfs and will make the
transition to a no-libsysfs world smoother.
