Hmm sorry about that. I thought I had based it against that day's
tip/master.

The patch itself looks ok, but it doesn't seem to apply to a recent
kernel tree. It appears as though it is white-space damaged. Would you
mind re-sending it?
Hmm sorry about that. I thought I had based it against that day's tip/master.
Anyway, here is v3 which is against tip/master as of

This is really about simplifying the double xchg patterns into
a single cmpxchg, with the same logic. Other than the immediate
cleanup, there are some subtleties this change deals with:
(i) While the load of the old bt is fully ordered wrt everything,
ie:
old_bt = xchg(>blk_trace, bt);
This is really about simplifying the double xchg patterns into
a single cmpxchg, with the same logic. Other than the immediate
cleanup, there are some subtleties this change deals with:
(i) While the load of the old bt is fully ordered wrt everything,
ie:
old_bt = xchg(>blk_trace, bt);
