Comment # 2 on bug 1066090 from Bin Liu

Hi, is this what you want?
sam.c: In function ���sam_cmap_update_key���:
sam.c:155:46: warning: ���%s��� directive output may be truncated writing 8 bytes
into a region of size between 1 and 255 [-Wformat-truncation=]
   snprintf(key_name, CMAP_KEYNAME_MAXLEN, "%s%s",
sam_internal_data.cmap_pid_path,
                                              ^~
     "recovery");
     ~~~~~~~~~~                                
sam.c:155:3: note: ���snprintf��� output between 9 and 263 bytes into a destination
of size 255
   snprintf(key_name, CMAP_KEYNAME_MAXLEN, "%s%s",
sam_internal_data.cmap_pid_path,
  
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     "recovery");

the code is as following:
char key_name[CMAP_KEYNAME_MAXLEN];

        switch (key) {
        case SAM_CMAP_KEY_RECOVERY:
                svalue = ssvalue[SAM_RP_MASK
(sam_internal_data.recovery_policy)];

                snprintf(key_name, CMAP_KEYNAME_MAXLEN, "%s%s",
sam_internal_data.cmap_pid_path,
                                "recovery");
