Please take a look and comment. So it looks like you've gone with 4a072c71f49. If that looks good (moving the lock, etc) to you, then great, we're done. If there are still locking objections (are there?), then we'll need to revisit. > but I didn't send the pull request to Linus because I was waiting to > see about how discussions over the locking strategy and the spammy log > messages on PowerPC was going to get resolved. > The other open issue I want to resolve before sending a pull request > this week is whether we want to change the default for > CONFIG_WARN_UNSEEDED_RANDOM so that the answer is 'n'. In the v1 of this patch many moons ago, it was just vanilla, default y, but due to the spamminess, I thought folks would revolt. So I made a change: Specifically, I added `depends on DEBUG_KERNEL`. This means that these useful warnings will only poke other kernel developers. This is probably exactly what we want. If the various associated developers see a warning coming from their particular subsystem, they'll be more motivated to fix it. Ordinary users on distribution kernels shouldn't see the warnings or the spam at all, since typically users aren't using DEBUG_KERNEL. Then, to make things _even less_ annoying to kernel developers, you added a nice patch on top to squelch repeated messages. So, I still think this current strategy is a good one, of default y, but depends on DEBUG_KERNEL. Regards, Jason
