| |
This post applies to vanilla 2.4.18.
It looks to me like nfs_create_request() is assigning to policy instead of or'ing the yield bit effectively converting real time tasks (SCHED_FIFO=2 and SCHED_RR=1) into normal tasks (SCHED_OTHER=0).
If I'm overlooking something trivial just hit me with the cluebat, otherwise trivial patch follows.
