It applies cleanly to 6.12.y. Thanks, Queued for 6.12.y, thanks. Note that e1b849cfa6b6 introduced a use-after-free in inode_switch_wbs_work_fn() that was fixed later by 6689f01d6740 ("writeback: Fix use after free in inode_switch_wbs_work_fn()", which carries Fixes: e1b849cfa6b6 and Cc: stable). That fix wasn't in 6.12.y yet either, so I've queued it on top to avoid reintroducing the UAF. -- Thanks, Sasha
