This new change seems to be more intrusive than should be needed.
Can't we just do:
__sched int bit_wait(struct wait_bit_key *word)
{
+ long state = current->state;
- if (signal_pending_state(current->state, current))
- return 1;
schedule();
+ if (signal_pending_state(state, current))
+ return -EINTR;
return 0;
}
??
(and sorry for breaking this in the first place!)
