Agreed.

I'll take the patch and merge it into maint. Note, what I'm going to try to do is to take entire patches of yours at once, although in some cases they will be applied to different branches (or split into different patches). The goal will be to not disturb things too badly if you do any further work on the patch series, since git-rebase should be smart enough. However, it might be a good idea for you to set a tag on what you've pushed so far, and to save everything past that point as diffs in case git rebase doesn't work out for whatever reason. Hopefully while I'm in Japan and/or over Thanksgiving weekend I'll have enough time to merge all of these patches into mainline. (I'll probably miss next week's conference call as well since I'll be in Tokyo, BTW. If someone can take notes during the call, or at least for anything that needs my attention, I'd appreciate it.) - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
