Strange that this hit in the USB tree. It's possible this is another variant of the problems introduced by the maple tree bug fixed in [0] as this has been seen to result in hanged processes due to memory corruption. This is sitting in the unstable hotfixes branch in mm so not yet in an rc, so it is possible. The issue is that it manifests in potentially unpredictable ways so it may be this or it may not. In any case the vma_link_file() stall seems likely to be due to contended lock, and since we are pulling the address_space against which we take that lock from a vma, which could be a UAF due to the bug, this seems plausible. On the other hand, I notice that CONFIG_DEBUG_VM_MAPLE_TREE is enabled here which causes very expensive validation (not in vma_link_file() but elsewhere) which can cause RCU stalls.
