Title
NFSv4/pnfs: Fix a use-after-free bug in open
Summary
In the Linux kernel, the following vulnerability has been resolved: NFSv4/pnfs: Fix a use-after-free bug in open If someone cancels the open RPC call, then we must not try to free either the open slot or the layoutget operation arguments, since they are likely still in use by the hung RPC call.
