If anyone has any objections, please let me know. ------------------ From: Jiri Slaby (SUSE) [ Upstream commit 1241b384efa53f4b7a95fe2b34d69359bb3ae1b5 ] In tty, u8 is now used for data, ssize_t for sizes (with possible negative error codes). Propagate these types to 6pack. Signed-off-by: Jiri Slaby (SUSE) Cc: Greg Kroah-Hartman Cc: Andreas Koensgen Cc: David S.
