[eudev] Unbind eudev of btrfs

[Александр Паутов]

Hello!

Starting with version 1.10-r2 eudev requires header btrfs.h. But kernel
version 3.4 there is no such header.
eudev-1.9-r2 is marked as unused. Can I somehow decouple from eudev
btrfs.h?

I use gentoo on cubietruck.
$ uname -a
Linux cumini 3.4.104-sun7i-1 + # 1 SMP PREEMPT Fri Sep 26, 2014 00:13:50

I don't know if that is that is possible but anyway you'll now need
ay least kernel version 3.7 if i understand well as noted in the NEWS
file shipped in source tarball for systemd 1.10 and in this announce:
http://lists.freedesktop.org/archives/systemd-devel/2014-October/024662.html

* Userspace firmware loading support has been removed and
   the minimum supported kernel version is thus bumped to 3.7.

What have systemd?
Ebuild in eudev-1.10-r2 contains the minimum kernel version 2.6.39.
Why would include btrfs.h tough? Why not make the use-flag?

Maybe I was wrongly assuming that the need of kernel
version 3.7 for firmware loading support implied the same
need for udev as for systemd?

I'll let other people respond as I'm not a developer.

Forgive me if impolite wrote.
It seems to find where to fix. Make a temporary patch. Eudev compiled
without btrfs.h. I will test what happened.

I can fix this.  If you tell me what decls it needs i'll be able to add 
the configure check.

Hi Александр,

You were not impolite at all!

My question (admittedly off topic and now answered by Anthony) was
genuine as I wrote that in a forum post:
http://www.linuxquestions.org/questions/slackware-14/%5Bannounce%5D-eudev-for-slackware-14-1-is-available-for-testing-purposes-4175505218/#post5262869
and wondered if what I wrote was accurate.

By the way Anthony, I have no bug or weirdness report yet coming from
users of eudev 2.1.1 for Slackware 14.1: so far so good, thanks to you
and the whole team!

Best regards,
Didier

PS: Александр, our Slint project now provides polyglot installers and
administration tools for Slackware in Russian an Ukrainian among other
languages, see:
http://slint.fr
if you want to try it.

1) userland firmware loading has been removed from eudev too, but that's 
not what's going on here.

2) always feel free to respond.  i depend on the community for feedback.

This can be fixed.  You test for the presence of btrfs.h and if it 
doesn't exist, you add the missing decls.

Yes we can. Can you open a bug at https://github.com/gentoo/eudev/issues 
so we have a record of this and I don't forget.
