  "description": "In the Linux kernel, the following vulnerability has been resolved:  blk-cgroup: save IRQ state in blkg_tryget_closest()  bio_set_dev() associates the bio with a blkg through bio_associate_blkg(). If the blkg lookup misses, blkg_tryget_closest() takes q-\u003Equeue_lock with spin_lock_irq() and releases it with spin_unlock_irq(), which unconditionally enables local interrupts.  Callers may call bio_set_dev() with interrupts already disabled, e.g. dm-thin\u0027s pool_map() does so while holding pool-\u003Elock taken with spin_lock_irq().  The nested spin_unlock_irq() then enables interrupts while pool-\u003Elock is still held, so an I/O completion softirq can run on the same CPU, re-acquire pool-\u003Elock (thin_endio(), or overwrite_endio() -\u003E complete_mapping_preparation()) and deadlock.  lockdep reports this as inconsistent SOFTIRQ-ON-W to IN-SOFTIRQ-W usage.  Commit 3a762de55b4e (\u0022block: save irq state in blkg_lookup_create()\u0022) fixed the same problem while the lock lived in blkg_lookup_create(), but commit 9327a865e395 (\u0022blk-cgroup: don\u0027t nest queue_lock under rcu in blkg_lookup_create()\u0022) moved the locking into blkg_tryget_closest() and reverted it to spin_lock_irq().  Save and restore the caller\u0027s IRQ state instead.",
