Hi!
From: Alexander Potapenko glider@google.com
[ Upstream commit f630a5d0ca59a6e73b61e3f82c371dc230da99ff ]
KMSAN metadata for adjacent physical pages may not be adjacent, therefore accessing such pages together may lead to metadata corruption. We disable merging pages in biovec to prevent such corruptions.
KMSAN is not there at least in 5.10, so we should not have this in -stable.
Best regards, Pavel
