Rex Zhang e23d6ba502 dmaengine: idxd: Move dma_free_coherent() out of spinlocked context ... [ Upstream commit e271c0ba3f ] Task may be rescheduled within dma_free_coherent(). So dma_free_coherent() can't be called between spin_lock() and spin_unlock() to avoid Call Trace: Call Trace: <TASK> dump_stack_lvl+0x37/0x50 __might_resched+0x16a/0x1c0 vunmap+0x2c/0x70 __iommu_dma_free+0x96/0x100 idxd_device_evl_free+0xd5/0x100 [idxd] device_release_driver_internal+0x197/0x200 unbind_store+0xa1/0xb0 kernfs_fop_write_iter+0x120/0x1c0 vfs_write+0x2d3/0x400 ksys_write+0x63/0xe0 do_syscall_64+0x44/0xa0 entry_SYSCALL_64_after_hwframe+0x6e/0xd8 Move it out of the context.
