Ok, if I drop this one, I think I need to drop an ext4 patch as well, I'll go figure that out and respin a -rc2 with this change in it. 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/

Ok, I've dropped this one, and the two ext4 patches after this one as well. If someone wants them back, please feel free to redo them so that they apply to the .27 tree now. 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/

If someone wants to get this bug fixed for the .27 tree, please feel free to send me the patches. Personally, I doubt many people care about ext4 on the .27 kernel release... 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/

It can't be reverted directly (you'll get a build failure) since the next ext4 patch in this -stable series depends on it. There's a commit from Ted Ts'o in the ext4 git, "ext4: Use our own write_cache_pages()", which removes the dependency, but that patch is not yet in mainline so isn't a -stable candidate. When/if that patch hits mainline, it can be added to -stable and this patch dropped/reverted.
