+Subject: blk-throttle: fix UAF by deleteing timer in blk_throtl_exit()
+
+From: Li Jinlin <lijinlin3@huawei.com>
+
+[ Upstream commit 884f0e84f1e3195b801319c8ec3d5774e9bf2710 ]
+
+The pending timer has been set up in blk_throtl_init(). However, the
+timer is not deleted in blk_throtl_exit(). This means that the timer
+handler may still be running after freeing the timer, which would
+result in a use-after-free.
+
+Fix by calling del_timer_sync() to delete the timer in blk_throtl_exit().

+
+[ Upstream commit aac6c0f90799d66b8989be1e056408f33fd99fe6 ]
+
+The xilinx dma driver uses the consistent allocations, so for correct
+operation also set the DMA mask for coherent APIs. It fixes the below
+kernel crash with dmatest client when DMA IP is configured with 64-bit
+address width and linux is booted from high (>4GB) memory.

+
+If kobject_init_and_add return with error, then the cleanup of kobject
+is needed because memory may be allocated in kobject_init_and_add
+without freeing.
+
+And the place of cleanup_dev_kobject should use kobject_put to free the
+memory associated with the kobject. As the section "Kobject removal" of
+"Documentation/core-api/kobject.rst" says, kobject_del() just makes the
+kobject "invisible", but it is not cleaned up. And no more cleanup will
+do after cleanup_dev_kobject, so kobject_put is needed here.

+From: Nanyong Sun <sunnanyong@huawei.com>
+
+[ Upstream commit 17243e1c3072b8417a5ebfc53065d0a87af7ca77 ]
+
+kobject_put() should be used to cleanup the memory associated with the
+kobject instead of kobject_del(). See the section "Kobject removal" of
+"Documentation/core-api/kobject.rst".

+Subject: nilfs2: fix NULL pointer in nilfs_##name##_attr_release
+
+From: Nanyong Sun <sunnanyong@huawei.com>
+
+[ Upstream commit dbc6e7d44a514f231a64d9d5676e001b660b6448 ]
+
+In nilfs_##name##_attr_release, kobj->parent should not be referenced
+because it is a NULL pointer. The release() method of kobject is always
+called in kobject_put(kobj), in the implementation of kobject_put(), the
+kobj->parent will be assigned as NULL before call the release() method.
+So just use kobj to get the subgroups, which is more efficient and can fix
+a NULL pointer reference problem.

+
+A consumer is expected to disable a PWM before calling pwm_put(). And if
+they didn't there is hopefully a good reason (or the consumer needs
+fixing). Also if disabling an enabled PWM was the right thing to do,
+this should better be done in the framework instead of in each low level
+driver.
