From 2f69335710884ae6112fc8196ebe29b5cda7b79b Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 3 Jan 2013 15:53:02 +0100 Subject: TTY: convert more flipping functions Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty pointer in many call sites. Only tty_port will be needed and hence no more tty_port_tty_get calls in those paths. Now 4 string flipping ones are on turn: * tty_insert_flip_string_flags * tty_insert_flip_string_fixed_flag * tty_prepare_flip_string * tty_prepare_flip_string_flags Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman --- include/linux/tty_flip.h | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-) (limited to 'include/linux/tty_flip.h') diff --git a/include/linux/tty_flip.h b/include/linux/tty_flip.h index 78207ca8fab1..743f1d076467 100644 --- a/include/linux/tty_flip.h +++ b/include/linux/tty_flip.h @@ -2,10 +2,14 @@ #define _LINUX_TTY_FLIP_H extern int tty_buffer_request_room(struct tty_port *port, size_t size); -extern int tty_insert_flip_string_flags(struct tty_struct *tty, const unsigned char *chars, const char *flags, size_t size); -extern int tty_insert_flip_string_fixed_flag(struct tty_struct *tty, const unsigned char *chars, char flag, size_t size); -extern int tty_prepare_flip_string(struct tty_struct *tty, unsigned char **chars, size_t size); -extern int tty_prepare_flip_string_flags(struct tty_struct *tty, unsigned char **chars, char **flags, size_t size); +extern int tty_insert_flip_string_flags(struct tty_port *port, + const unsigned char *chars, const char *flags, size_t size); +extern int tty_insert_flip_string_fixed_flag(struct tty_port *port, + const unsigned char *chars, char flag, size_t size); +extern int tty_prepare_flip_string(struct tty_port *port, + unsigned char **chars, size_t size); +extern int tty_prepare_flip_string_flags(struct tty_port *port, + unsigned char **chars, char **flags, size_t size); void tty_schedule_flip(struct tty_struct *tty); static inline int tty_insert_flip_char(struct tty_struct *tty, @@ -17,12 +21,12 @@ static inline int tty_insert_flip_char(struct tty_struct *tty, tb->char_buf_ptr[tb->used++] = ch; return 1; } - return tty_insert_flip_string_flags(tty, &ch, &flag, 1); + return tty_insert_flip_string_flags(tty->port, &ch, &flag, 1); } static inline int tty_insert_flip_string(struct tty_struct *tty, const unsigned char *chars, size_t size) { - return tty_insert_flip_string_fixed_flag(tty, chars, TTY_NORMAL, size); + return tty_insert_flip_string_fixed_flag(tty->port, chars, TTY_NORMAL, size); } #endif /* _LINUX_TTY_FLIP_H */ -- cgit v1.2.3
