I really do want the whole "there can be only one" highlander part. Go all Christopher Lambert on it, and cut it off at the head so that it cannot resurface even by mistake. IOW, remove the config option entirely, and remove the #ifdef's that switch between the BKL and mutex case. Otherwise somebody will enable the BKL code, and we'll miss the testing for that case. And getting testing is what the whole merge window is all about. I also don't want the BKL to show up in grep, even if the config option for it were to be impossible to enable. If we've gotten far enough that we can get rid of the BKL in the tty layer, we really should get rid of it. Not leave it in some zombie limbo state.

Ok, I've sent the replacement patch that does this, and I'm much happier with the outcome. If you apply this version, the only stronghold left for the BKL will be fs/lockd, everything else that's left is either simple to fix or highly obscure.

Didn't we have patches for fs/lockd/ too? Or am I just confused with the fs/locks.c patches?

Or am I just confused with > the fs/locks.c patches? I had a ten-year old patch from Willy that takes care of fs/locks.c, but we can't apply that without also taking care of fs/lockd. I first didn't realize this when I sent that patch.

Ok, I got that one now, and am building the tree to test here before sending to Linus. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
