[PATCH] 9p: safer definition of P9_NOTAG and P9_NOFID

Show all headers | View raw

Both defines should at least have enclosing parenthesis to be usable in
any syntactical situation. This is the case of U16_MAX and U32_MAX, so
let's use them.

This patch is just cleanup, it doesn't change any behaviour with the current
code.
