Hmm, not sure if I read this diff correcty, but it seems to remove struct zone and spinlock, which would not be right, and introduce a new bug. The reason why the upstream commit does not apply directly to bionic, is because of conflicting context. The "struct zone" was replaced with "pg_data_t *pgdat" by (another) commit 92fb1db26eef, but that change (or any change to the struct zone) would not be necessary to fix the uninitialized struct page access. So, I would suggest simply replacing the line pg_data_t *pgdat; from the upstream commit context, with this line to fix the context for bionic struct zone *zone; Removing struct zone and the spinlock would certainly introduce a new bug, because the spinlock is necessary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904884 Title: s390: dbginfo.sh triggers kernel panic, reading from /sys/kernel/mm/page_idle/bitmap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1904884/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
