This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd Cc: Greg Kroah-Hartman Cc: Al Viro Cc: Julia Lawall Acked-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/misc/ibmasm/ibmasmfs.c | 8 +------- 1 file changed, 1 insertion(+), 7 deletions(-) (limited to 'drivers/misc/ibmasm/ibmasmfs.c') diff --git a/drivers/misc/ibmasm/ibmasmfs.c b/drivers/misc/ibmasm/ibmasmfs.c index 1c034b80d408..6673e578b3e9 100644 --- a/drivers/misc/ibmasm/ibmasmfs.c +++ b/drivers/misc/ibmasm/ibmasmfs.c @@ -500,12 +500,6 @@ static ssize_t r_heartbeat_file_write(struct file *file, const char __user *buf, return 1; } -static int remote_settings_file_open(struct inode *inode, struct file *file) -{ - file->private_data = inode->i_private; - return 0; -} - static int remote_settings_file_close(struct inode *inode, struct file *file) { return 0; @@ -600,7 +594,7 @@ static const struct file_operations r_heartbeat_fops = { }; static const struct file_operations remote_settings_fops = { - .open = remote_settings_file_open, + .open = simple_open, .release = remote_settings_file_close, .read = remote_settings_file_read, .write = remote_settings_file_write, -- cgit v1.2.3
