My 3.1 (after) rc10 crashed (there was no xfs changes after it afaik).

Could anyone verify that this isn't some nasty xfs problem since it's close to final 3.1? Happened only once.

No quota was used, xfs on top of luks on top of ssd drive.

It looks to be caused by a general protection fault, and giving the place where this crashed I would say this sounds like the bug I've fixed some days ago related with the size of the symlinks.
I can be wrong though, and this is related with another problem.

The weird thing is that I never ever hit this before with pre 3.1rc10 git kernels. Was your bugfix a fix for new issue that was introduced in 3.1 cycle or for something old?

Hmm, sorry, my mistake here, I fixed a problem on xfs_readlink, not at xfs_symlink.

Although, by your last screenshots, it doesn't look to be related with the problem I was working before.

On all screenshots the system is crashing while trying to acquire a mutex lock, I don't know much about the code path where the crash is happening, but, maybe if you enable CONFIG_XFS_DEBUG we can get some extra hints about where the system is crashing? Also, have you fsck'ed this FS? maybe an xfs_repair -nv would give any clue if there is any corrupted metadata which would cause this error

And my mistake here. I had applied "RFC Allow pquota and gquota to be used together" to the wrong tree (daily use tree) instead of testing tree.

So something in that patch series is causing such problem.
