You can't call this without having it set in all schedulers.
I guess using the init_pdata hook has to be introduced after or in
patch 5.
But, if it is not set, it is NULL, in which case, SCHED_OP does the
trick for me, doesn't it?
#define SCHED_OP(opsptr, fn, ...) \
(( (opsptr)->fn != NULL ) ? (opsptr)->fn(opsptr, ##__VA_ARGS__ ) \
: (typeof((opsptr)->fn(opsptr, ##__VA_ARGS__)))0 )
Aah, yes, of course.
Sorry for the noise.
