2.6.35-helium0: patch, broken-out and precompiled.
Contains reiser4 (upstream), aufs2 (git-20100802), tuxonice (git-2010805), fbcondecor (0.9.6-2.6.35-rc4).
Reiser4 is broken for me. It segfaults while unmounting (and doesn't sync before unmounting). So I would not recommend it to anyone using Reiser4. (Please note that this was while mounting and unmounting a reiser4 formatted file as a loop device.) Some dmesg details indicate problems due to changes in kernel/exit.c:
| Code: | reiser4: loop2: found disk format 4.0.0.

As I usually cc these messages to maintainer cause none else will, I got this back:
"loop is over a file on what file system?
Doesn't he want to fsck the last one?"

@dusanc: Thank you for cc'ing the kernel messages to upstream (assuming I understand you correctly). The loop is over an ext3 file system, and here are the steps to reproduce:
| Code: | # dd if=/dev/zero of=abc.rfs bs=1024 count=500000 # Create a 512 MB file, and assuming current directory is on a ext3 filesystem.
# mkfs.reiser4 -f abc.rfs # Force format this file with Reiser4.
# mkdir -p /mnt/test && mount abc.rfs /mnt/test/ -o loop # Mount this file as a loop device.
# cp /boot/vmlinuz /mnt/test # Copy some file.
# umount /mnt/test # Try to unmount quickly, potentially before filesystem syncs, and we should get a Segmentation fault. |
And the same kernel messages:
| Code: | reiser4: loop2: found disk format 4.0.0.

Edit 1: Would be happy to provide more information if needed. Other (possibly irrelevant) information: using sys-apps/util-linux-2.18-r1. And my kernel has CONFIG_NUMA=y (seems some numa specific code has changed in kernel/exit.c.)
Edit 2: And this doesn't happen when I use another filesystem like hfsplus instead of reiser4.

Would be nice if we could cut the man in the middle 
Can you report it directly to reiserfs-devel, would be much faster?

Very true, it feels silly on my part to make someone report it. I'll try to report to reiserfs-devel directly. Just that I hate to join a new mailing list each time.

I am a daredevil (I got backup power), so I'll just add that Reiser4 works just fine when it's your main filesystem of choice. :P
Unfortunately I can't stick to 2.6.35, it has a strange bug with my wireless card where it gives me microcode errors :S Probably will have to report it as I can't find any references to it online. |

Hi. Every time I try to compile openoffice in 3 threads using reiser 4 partition I get the following kernel error and always in the same place, specifically where some java part of openoffice is being compiled

Unfortunately my mails to reiserfs-devel don't seem to get delivered to the list so I'm posting it in this thread. |

The wireless card mysteriously resolved itself after many reinstalls of different parts of the wireless stack :[
Anyway, I reverted back to the previous version because Reiser4 seems to have a few problems! Last time I suspended to RAM after compiling a few packages, one of the files included by the compile (in /usr/include/) process got "one character changed" (I think it was an underscore that became an opening bracket), which then caused compilation to fail until I fixed the file. How did a system include file owned by root got modified while a user-process was executing (and said file was open read-only)? :/
Because the errors caused by this kind of bug could be undetectable (and things just randomly start failing) I had to revert back to the previous kernel version. Hopefully the other reported bugs are somehow tied, so that fixing them will resolve all my issues. I'll try again for 2.6.36. |

Hi. I am only posting here because....

resulted in empty files and "orphan" items. The problem took place only
for splice users (loop devices, pipe2, etc).
. Implemented ->sync_fs() method of super operations. Since introducing a
new per-bdi flushing stuff reiser4 wasn't able to perform sync on umount.
Now such sync is performed by reiser4_sync_fs().
. Fixed an old bug which led to non-deletable directories.
. Fixed an old bug in tail conversion, which led to data corruption when
running in disk space pressure situations. |

And I am excited about it. |

I recently decided to uninstall gentoo-sources (since I am not using any other kernel than Helium), but now Portage bugs me that it needs some default kernel installed in order to update my nvidia-drivers :/
So I went ahead and wrote a small ebuild for this. Can we not put it as a "quote" or "code" block in the first post? I'll gladly take care of any inquiries or problems that arises from the ebuild. It should work for all kernel versions (as long as it's helium0, otherwise one char needs to be changed within).

Saved as helium-sources-2.6.36.ebuild works just fine for me.
PS: I was thinking of using the revision as the version of the patchset (eg: helium-sources-2.6.36-r2 would be helium2), but I don't think this convention falls into the Gentoo guidelines. :B |

@ Skotlex: Thanks for the ebuild and suggestions. Hopefully I will find some time today and clean things up.

Here is my take on an ebuild, which you can also get from here. Since I have written it more as a bash script, let me know if there have been any potential abuses on my part.
1. Copy and digest this ebuild as "helium-sources-2.6.36.ebuild" or "helium-sources-2.6.36-rX.ebuild" (where X=1,2,3, etc) in sys-kernel/helium-sources/ of your local overlay. Emerging it will fetch the latest 2.6.36.X vanilla kernel patches (along with the reiser4, aufs patches etc of course). So next time a minor update to stable kernel comes out, just bump the revision of this ebuild. The corresponding kernel source is installed with version 2.6.36-helium or 2.6.36-helium-rX.
2. True to Gentoo's configurability, depending on the features you need, the ebuild supports the USE flags "resier4 aufs tuxonice fbcondecor config". (It is more for fun than for any serious purpose.)

As is routine, here is a initial version of 2.6.37-helium0: patch, broken-out and precompiled.
And as can be seen from previous posts, now there is also an ebuild here, that supports different patches as USE flags: | Code: | | [ebuild N ] sys-kernel/helium-sources-2.6.37 USE="aufs config fbcondecor reiser4 tuxonice -build -symlink" 413 kB [1] |
. For point updates 2.6.37.X, just rename the ebuild to helium-sources-2.6.37-rX.ebuild.
Also as usual, it does not contain reiser4 at the moment and will be added if and when released upstream. For now, it contains aufs2 (from aufs 2.1-standalone.tree-37-rcN-20110110), tuxonice (3.2-rc2), fbcondecor (0.9.6-2.6.36-rc8). All tested OK.

And as usual, I am reporting that the stable patch for R4 is already out (actually, it was just released yesterday, the 26th). :P
Can't wait to update, once more. |

I have updated to include the reiser4 patch. If using the ebuild, please remove the old Manifest and distfiles and do a fresh ebuild digest. Also, as mentioned earlier, for future point releases of vanilla 2.6.37.X, just rename the ebuild to helium-sources-2.6.37-rX.ebuild and perform the rituals.

Funny, I've been tracking the R4 release for a while, and the same morning it finally comes out for 2.6.38, you also released this update. I am starting to suspect I may be the sole user of this patch-set? :P
In any case, your ebuild worked wonders to update! Such a breeze. |

@ Skotlex: It was a coincidence that it came out on a weekend, when I usually look around. I am happy that at least someone uses this "patchset". BTW, there are just 4 patches, all maintained very well upstream and it is trivial to put them together on my part, so calling it a "patchset" is a bit of a stretch. Still, glad that I have done a working ebuild (by copying from other ones).
