That patch should help. > OK. This bug seems to exist since commit ca94c442535a "sched: Introduce SCHED_RESET_ON_FORK scheduling policy flag". Should Cc: <stable@xxxxxxxxxxxxxxx> [2.6.32+] line be added? By the way, does use of "unsigned char" than "unsigned" save some bytes? Simply trying not to change the size of "struct task_struct"...
