Hi,

it seems that a bug was backported into the latest 2.6.32 longterm stable kernel. Now the patch "XFS: accounting of reclaimable inodes is incorrect" needs to get backported to 2.6.32.

Who can help? Who is responsible?

Please CC me i'm not on list.

For -stable releases no one really is. If you want to help you can backport it and send it to the stable mailinglist.

Sorry i can't. I'm not a kernel hacker. But i think a real bug / showstopper should be fixed in a longterm stable kernel.

Redhat seems to have fixed it on it's own:
https://bugzilla.redhat.com/show_bug.cgi?id=642680

Sadly they haven't provided a patch.

Linux 2.6.32 isn't really something supported by us. It's not just a very old codebase, but also one where a lot of the XFS code was pretty much in flux. If you want supported old releases work use one of the commercially supported one like RedHat or SuSE.

I suspect the upstream commit you want is 081003fff467ea0e727f66d5d435b4f473a789b3, but I can't gurantee this actually applies to the 2.6.32 codebase.

OK so my thought was totally wrong. I thought the longterm stable releases will still get bugfixed by SGI or whoever wrote the stuff. Sorry for that then. But what is then the idea of a longterm stable?

No it doesn't. I already tried to implement it into current 2.6.32.41 code.

I have no idea what the idea is, but it's clearly not viable for normal kernel developers. Backporting code to age old releases and QAing it is a major effort, and people generally don't do it unless they are paid for it.

2.6.32 is also the kernel in Ubuntu 10.04 LTS
