CVE-2024-35974

In the Linux kernel, the following vulnerability has been resolved: block:
fix q->blkg_list corruption during disk rebind Multiple gendisk instances
can allocated/added for single request queue in case of disk rebind. blkg
may still stay in q->blkg_list when calling blkcg_init_disk() for rebind,
then q->blkg_list becomes corrupted. Fix the list corruption issue by: -
add blkg_init_queue() to initialize q->blkg_list & q->blkcg_mutex only -
move calling blkg_init_queue() into blk_alloc_queue() The list corruption
should be started since commit f1c006f1c685 (“blk-cgroup: synchronize
pd_free_fn() from blkg_free_workfn() and blkcg_deactivate_policy()”) which
delays removing blkg from q->blkg_list into blkg_free_workfn().
