Add P9_ERRMAX macro to 9P protocol header which reflects the maximum error string length of Rerror replies for 9p2000 and 9p2000.u protocol versions. Unfortunately a maximum error string length is not defined by the 9p2000 spec, picking 128 as value for now, as this seems to be a common max. size for POSIX error strings in practice. 9p2000.L protocol version uses Rlerror replies instead which does not contain an error string. Signed-off-by: Christian Schoenebeck <linux_oss@crudebyte.com> --- This could probably be merged with the next patch, on doubt I posted it separately as squashing is easy. The advantage of a separate patch is making the discussion of the chosen value of max. 128 bytes more prominent. include/net/9p/9p.h | 3 +++ 1 file changed, 3 insertions(+)
