chattr does not understand nodatacow / COW_No option "+C"

Bug Description

on btrfs:

mdkir vbox
chattr +C vbox


Aufruf: chattr [-RVf] [-+=AacDdeijsSu] [-v Version] Dateien...

-> Precises 1.42-1 e2fsprogs do not understand +C / -C option.

The manpage does also not contain documentation for it. The status für the ext2 ext3 systems (not honoring transparent compression) is also a strong indicator that e2fsprogs on precise are outdated, as btrfs is not even mentioned now supporting lzo and more...

DO e2fsprogs actually incorporate btrfs support? Maybe upstream chattr must be taken out, as it is not ext-specific any more?

Support for chattr +C/-C was added to e2fsprogs 1.42.4.

The most recent version of e2fsprogs is v1.42.6.

Debian is shipping e2fsprogs 1.42.5.

Note that e2fsprogs 1.42.x is a maintenance release, so it would be useful for an Ubuntu LTS to consider upgrading to a newer version of e2fsprogs, and to track the 1.42.x releases in general. (For example, I'm aware of a bug where users using the 64-bit feature of ext4 and fairly large RAID arrays can potentially lose data if they do an off-line resize using resize2fs. That fix will be in 1.42.7, once I get that fixed....)

Now 1.42.13 has been uploaded by mdeslaur. So could be closed?
