Specifically, it matters on very large configuration systems (i.e., 32GB-64GB using PAE-36) that today we'd probably just say, "use x86_64, you moron". It would probably matter if someone were to want to upgrade a non-64-bit capable machine to a newer kernel. Dropping nobh from ext3 at this point might prevent some of these older systems from upgrading, I'm not sure how much we would care; on the one hand, these machines tended to be pretty expensive, so people would probably want to use them for a while. On the other hand, it has been over five years now since x86_64 machines have been available, and many of these customers are highly unlikely to want to upgrade anyway. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
