CVE-2022-49316

NFSv4: Don't hold the layoutget locks across multiple RPC calls

In the Linux kernel, the following vulnerability has been resolved:

NFSv4: Don't hold the layoutget locks across multiple RPC calls

When doing layoutget as part of the open() compound, we have to be
careful to release the layout locks before we can call any further RPC
calls, such as setattr(). The reason is that those calls could trigger
a recall, which could deadlock.
