dmaprocs uses list to store all dmabufs of a process, during iterate_fd we loop through all the files of a process and check if each file is a dmabuf and if it is dmabuf we check if the list already contains this dmabuf we do this while holding a file_lock this could take time if the list is large and cause contention on the file_lock, so replace list with a hashtable so that this time is reduced.
