Re: [PATCH 2/3] ios: Move file name normalization logic into ios-dev.h

Hi Ege.

    +#define IOS_FILE_HANDLER_NORMALIZE(handler, newhandler)                    
\
    +{                                                                  \
    +  /* File devices are special, in the sense that they accept any   \
    +     handler. However, we want to ensure that the ios name is              
\
    +     unambiguous from other ios devices, by prepending ./ to relative      
\
    +     names that might otherwise be confusing.  */                  \
    +  static const char safe[] =                                               
\
    +    "abcdefghijklmnopqrstuvwxyz"                                   \
    +    "ABCDEFGHIJKLMNOPQRSTUVWXYZ"                                   \
    +    "0123456789/+_-";                                                      
\
    +                                                                   \
    +  if (handler[0] == '/' || strspn (handler, safe) == strlen (handler))     
\
    +    (newhandler) = strdup ((handler));                                     
\
    +                                                                   \
    +  if (asprintf (&(newhandler), "./%s", (handler)) == -1)           \
    +    (newhandler) = NULL;                                           \
    +}

Maybe it would be better to use a static inline function here?
Otherwise, please surround the macro body with do..while(0)

Other than that, OK for master.
Thanks! :)
