Analyze and fix the following issue in the Linux kernel code: 9p: fix error path during early mount
Problem Details: There was some cleanup issues during early mount which would trigger a kernel bug for certain types of failure. This patch reorganizes the cleanup to get rid of the bad behavior. This also merges the 9pnet and 9pnet_fd modules for the purpose of configuration and initialization. Keeping the fd trans...

Problem Details: The official reason is "with the presence of pid namespaces in the kernel using pid_t-s inside one is no longer safe."
