# first bad commit: [7c1e132b0967210526de05e7af6f1c26ad0c1516] sysfs: Introduce a mechanism to hide static attribute_groups
Thanks for bisecting this.
I think the problem is, that if you take this patch for stable, you need to also take the patch which is upstream [ cd69fedf58f8ab1ab511f7c6ac1969cebf1c935f] sysfs: Fix crash on empty group attributes array. It addresses the exact crash that I've run into.
Rather than adding cd69fedf58f8, I dropped d87c295f599c ("sysfs: Introduce a mechanism to hide static attribute_groups") and its dependent c7fbb8218b4a ("sysfs: check visibility before changing group attribute ownership") from the 6.6 and 6.1 queues.
Yeah, that seems to be the cleaner approach. I just tested this, and this works fine, too.
Will there be an -rc2?
Based on all of the reports, yes.
