  "description": "In the Linux kernel, the following vulnerability has been resolved:  block: Fix potential deadlock in blk_ia_range_sysfs_show()  When being read, a sysfs attribute is already protected against removal with the kobject node active reference counter. As a result, in blk_ia_range_sysfs_show(), there is no need to take the queue sysfs lock when reading the value of a range attribute. Using the queue sysfs lock in this function creates a potential deadlock situation with the disk removal, something that a lockdep signals with a splat when the device is removed:  [  760.703551]  Possible unsafe locking scenario: [  760.703551] [  760.703554]        CPU0                    CPU1 [  760.703556]        ----                    ---- [  760.703558]   lock(\u0026q-\u003Esysfs_lock); [  760.703565]                                lock(kn-\u003Eactive#385); [  760.703573]                                lock(\u0026q-\u003Esysfs_lock); [  760.703579]   lock(kn-\u003Eactive#385); [  760.703587] [  760.703587]  *** DEADLOCK ***  Solve this by removing the mutex_lock()/mutex_unlock() calls from blk_ia_range_sysfs_show().",
