Currently, we just print the numerical value of 9p operation identifier in case of RERROR which is less meaningful for readability. Mapping 9p operation ids to symbolic names provides a better tracelog: RERROR (tag = 1 , id = TWALK , err = " No such file or directory ") RERROR (tag = 1 , id = TUNLINKAT , err = " Directory not empty ") This patch provides a dictionary of all possible 9p operation symbols mapped to their numerical identifiers which are likely to be used in future at various places in this script.
