When the cxl driver creates a context, it stores the pid of the calling task, and mistakenly increments the reference count of the struct pid twice, once through get_task_pid(), once through get_pid(). The reference count is only decremented once on detach. As a result, a struct pid is leaked and it reduces the number of processes that can run simultaneously by one. The fix is to simply remove the call to get_pid(). There is a separate patch for the kernel API, since it goes to different kernel versions.
