Subject: mm: fix VM_BUG_ON in __delete_from_swap_cache()
Date: Fri, 2 Sep 2022 20:26:38 +0100
Patch series "Folio fixes for 6.0".
This patch (of 2):
The recent folio conversion changed the VM_BUG_ON() to dump the folio
we're storing instead of the entry we retrieved. This was a mistake;
the entry we retrieved is the more interesting page to dump.
