The patch titled proc tty: switch synclink_gt to ->proc_fops has been removed from the -mm tree. Its filename was proc-tty-switch-synclink_gt-to-proc_fops.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: proc tty: switch synclink_gt to ->proc_fops From: Alexey Dobriyan <adobriyan@xxxxxxxxx> Signed-off-by: Alexey Dobriyan <adobriyan@xxxxxxxxx> Cc: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/char/synclink_gt.c | 74 ++++++++++++++++------------------- 1 file changed, 34 insertions(+), 40 deletions(-) diff -puN drivers/char/synclink_gt.c~proc-tty-switch-synclink_gt-to-proc_fops drivers/char/synclink_gt.c --- a/drivers/char/synclink_gt.c~proc-tty-switch-synclink_gt-to-proc_fops +++ a/drivers/char/synclink_gt.c @@ -60,6 +60,7 @@ #include <linux/ptrace.h> #include <linux/ioport.h> #include <linux/mm.h> +#include <linux/seq_file.h> #include <linux/slab.h> #include <linux/netdevice.h> #include <linux/vmalloc.h> @@ -154,7 +155,6 @@ static void tx_hold(struct tty_struct *t static void tx_release(struct tty_struct *tty); static int ioctl(struct tty_struct *tty, struct file *file, unsigned int cmd, unsigned long arg); -static int read_proc(char *page, char **start, off_t off, int count,int *eof, void *data); static int chars_in_buffer(struct tty_struct *tty); static void throttle(struct tty_struct * tty); static void unthrottle(struct tty_struct * tty); @@ -1229,13 +1229,12 @@ static long slgt_compat_ioctl(struct tty /* * proc fs support */ -static inline int line_info(char *buf, struct slgt_info *info) +static inline void line_info(struct seq_file *m, struct slgt_info *info) { char stat_buf[30]; - int ret; unsigned long flags; - ret = sprintf(buf, "%s: IO=%08X IRQ=%d MaxFrameSize=%u\n", + seq_printf(m, "%s: IO=%08X IRQ=%d MaxFrameSize=%u\n", info->device_name, info->phys_reg_addr, info->irq_level, info->max_frame_size); @@ -1260,75 +1259,70 @@ static inline int line_info(char *buf, s strcat(stat_buf, "|RI"); if (info->params.mode != MGSL_MODE_ASYNC) { - ret += sprintf(buf+ret, "\tHDLC txok:%d rxok:%d", + seq_printf(m, "\tHDLC txok:%d rxok:%d", info->icount.txok, info->icount.rxok); if (info->icount.txunder) - ret += sprintf(buf+ret, " txunder:%d", info->icount.txunder); + seq_printf(m, " txunder:%d", info->icount.txunder); if (info->icount.txabort) - ret += sprintf(buf+ret, " txabort:%d", info->icount.txabort); + seq_printf(m, " txabort:%d", info->icount.txabort); if (info->icount.rxshort) - ret += sprintf(buf+ret, " rxshort:%d", info->icount.rxshort); + seq_printf(m, " rxshort:%d", info->icount.rxshort); if (info->icount.rxlong) - ret += sprintf(buf+ret, " rxlong:%d", info->icount.rxlong); + seq_printf(m, " rxlong:%d", info->icount.rxlong); if (info->icount.rxover) - ret += sprintf(buf+ret, " rxover:%d", info->icount.rxover); + seq_printf(m, " rxover:%d", info->icount.rxover); if (info->icount.rxcrc) - ret += sprintf(buf+ret, " rxcrc:%d", info->icount.rxcrc); + seq_printf(m, " rxcrc:%d", info->icount.rxcrc); } else { - ret += sprintf(buf+ret, "\tASYNC tx:%d rx:%d", + seq_printf(m, "\tASYNC tx:%d rx:%d", info->icount.tx, info->icount.rx); if (info->icount.frame) - ret += sprintf(buf+ret, " fe:%d", info->icount.frame); + seq_printf(m, " fe:%d", info->icount.frame); if (info->icount.parity) - ret += sprintf(buf+ret, " pe:%d", info->icount.parity); + seq_printf(m, " pe:%d", info->icount.parity); if (info->icount.brk) - ret += sprintf(buf+ret, " brk:%d", info->icount.brk); + seq_printf(m, " brk:%d", info->icount.brk); if (info->icount.overrun) - ret += sprintf(buf+ret, " oe:%d", info->icount.overrun); + seq_printf(m, " oe:%d", info->icount.overrun); } /* Append serial signal status to end */ - ret += sprintf(buf+ret, " %s\n", stat_buf+1); + seq_printf(m, " %s\n", stat_buf+1); - ret += sprintf(buf+ret, "\ttxactive=%d bh_req=%d bh_run=%d pending_bh=%x\n", + seq_printf(m, "\ttxactive=%d bh_req=%d bh_run=%d pending_bh=%x\n", info->tx_active,info->bh_requested,info->bh_running, info->pending_bh); - - return ret; } /* Called to print information about devices */ -static int read_proc(char *page, char **start, off_t off, int count, - int *eof, void *data) +static int synclink_gt_proc_show(struct seq_file *m, void *v) { - int len = 0, l; - off_t begin = 0; struct slgt_info *info; - len += sprintf(page, "synclink_gt driver\n"); + seq_puts(m, "synclink_gt driver\n"); info = slgt_device_list; while( info ) { - l = line_info(page + len, info); - len += l; - if (len+begin > off+count) - goto done; - if (len+begin < off) { - begin += len; - len = 0; - } + line_info(m, info); info = info->next_device; } + return 0; +} - *eof = 1; -done: - if (off >= len+begin) - return 0; - *start = page + (off-begin); - return ((count < begin+len-off) ?
