From c1b283d55d1806680e3ad1cfbef581afecbea5cb Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Mon, 7 Dec 2009 12:52:01 +0100 Subject: [S390] tape: remove f_pos changes from read / write function. The change to f_pos in the read / write method has no effect as the value is controlled by the VFS layer, e.g. for vfs_read: loff_t pos = file_pos_read(file); ret = vfs_read(file, buf, count, &pos); file_pos_write(file, pos); Signed-off-by: Martin Schwidefsky --- drivers/s390/char/tape_char.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'drivers/s390') diff --git a/drivers/s390/char/tape_char.c b/drivers/s390/char/tape_char.c index 31566c55adfe..b47e20d3d1da 100644 --- a/drivers/s390/char/tape_char.c +++ b/drivers/s390/char/tape_char.c @@ -170,7 +170,6 @@ tapechar_read(struct file *filp, char __user *data, size_t count, loff_t *ppos) if (rc == 0) { rc = block_size - request->rescnt; DBF_EVENT(6, "TCHAR:rbytes: %x\n", rc); - filp->f_pos += rc; /* Copy data from idal buffer to user space. */ if (idal_buffer_to_user(device->char_data.idal_buf, data, rc) != 0) @@ -238,7 +237,6 @@ tapechar_write(struct file *filp, const char __user *data, size_t count, loff_t break; DBF_EVENT(6, "TCHAR:wbytes: %lx\n", block_size - request->rescnt); - filp->f_pos += block_size - request->rescnt; written += block_size - request->rescnt; if (request->rescnt != 0) break; -- cgit v1.2.2
