Hello,
I asked over on 'users' a few days ago and no help yet. I hope you don't
mind my repeating the question here.
We're a small company using some altera-based boards and our own driver
to control them.
Fedora 7 was working well, but we are getting some unknown symbols while
evaluating an upgrade to F9.
Any help, comments, suggestions are greatly appreciated.

code and issues :
struct sched_param param = {70};
kernel_cap_t effective, inheritable, permitted, all;
cap_set_full(all); // be sure we have enough permissions to call
// sched_setscheduler.
// probably only need CAP_SYS_NICE, but let's be
// "(un)safe"
// save old permissions
cap_capget(current,&effective, &inheritable, &permitted);
// setup permissions to do this
cap_capset_set(current,&all, &all, &all);
// setup realtime priority
ret=sched_setscheduler(current,SCHED_RR,¶m);
// restore permissions
cap_capset_set(current,&effective, &inheritable, &permitted);
used to be able to do this in f7 / 2.6.23 kernel, now we get:
WARNING: "cap_capset_set" [/usr/CSM/src/ONI/oni_driver/oni.ko] undefined!
WARNING: "cap_capget" [/usr/CSM/src/ONI/oni_driver/oni.ko] undefined!
when building and of course:
oni: Unknown symbol cap_capget
oni: Unknown symbol cap_capset_set
when insmod'ing under f9 / 2.6.25
