Yes, the messaging involved with the "ext3" vs "ext4" bump has been really unfortunate. If I had to do it all over again, I would have created "ext3dev", and then when it was stable, I would done a: git rm -rf fs/ext3 ; git mv fs/ext3dev fs/ext4 =46or example, it would have avoided the problem with SuSE product managers refusing to support ext4 for multiple years, etc. It also would have avoided the problem with people doing comparisons of ext3 versus xfs, even in April 2014 (see a recent Hacker News promoted blog article, where in someone kvetched that ext3 didn't support fallocate). Sigh.... > What about just simply using mkefs.conf to specify the feature set > we want and use that? Yes, it's likely that for 1.43 we'll enable various features by default. It's been quite deliberate that I haven't enabled by default, because I wanted to make 100% sure they were completely stable before enabling them by default. Some of them we may have been able to enable by default earlier, but be that as it may, 1.43 is a good time to make that change. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
