The first patch of this series is the ioctl patch I posted before, with the review comments handled.
The rest of the series is enabling sysfs access to feature bits, similar to how ext4 publishes that information. Since we already have the online changing ability via the ioctl patch, we can also enable that via sysfs as well. /sys/fs/btrfs/features/ contains attributes for supported features, with the content indicating if the attribute is settable or clearable while mounted. /sys/fs/btrfs/<fsid>/features/ contains the attributes enabled on the file system plus attributes for features that can be changed online. The content indicates whether the feature is currently enabled. The permissions of the file also indicate whether it's changeable while online. I'll post updated tools patches separately. -Jeff -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
