From 234e340582901211f40d8c732afc49f0630ecf05 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 5 Apr 2012 14:25:11 -0700 Subject: simple_open: automatically convert to simple_open() Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. 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/net/wireless/wl1251/debugfs.c | 14 ++++---------- 1 file changed, 4 insertions(+), 10 deletions(-) (limited to 'drivers/net/wireless/wl1251/debugfs.c') diff --git a/drivers/net/wireless/wl1251/debugfs.c b/drivers/net/wireless/wl1251/debugfs.c index 6c274007d200..448da1f8c22f 100644 --- a/drivers/net/wireless/wl1251/debugfs.c +++ b/drivers/net/wireless/wl1251/debugfs.c @@ -47,7 +47,7 @@ static ssize_t name## _read(struct file *file, char __user *userbuf, \ \ static const struct file_operations name## _ops = { \ .read = name## _read, \ - .open = wl1251_open_file_generic, \ + .open = simple_open, \ .llseek = generic_file_llseek, \ }; @@ -84,7 +84,7 @@ static ssize_t sub## _ ##name## _read(struct file *file, \ \ static const struct file_operations sub## _ ##name## _ops = { \ .read = sub## _ ##name## _read, \ - .open = wl1251_open_file_generic, \ + .open = simple_open, \ .llseek = generic_file_llseek, \ }; @@ -117,12 +117,6 @@ out: mutex_unlock(&wl->mutex); } -static int wl1251_open_file_generic(struct inode *inode, struct file *file) -{ - file->private_data = inode->i_private; - return 0; -} - DEBUGFS_FWSTATS_FILE(tx, internal_desc_overflow, 20, "%u"); DEBUGFS_FWSTATS_FILE(rx, out_of_mem, 20, "%u"); @@ -235,7 +229,7 @@ static ssize_t tx_queue_len_read(struct file *file, char __user *userbuf, static const struct file_operations tx_queue_len_ops = { .read = tx_queue_len_read, - .open = wl1251_open_file_generic, + .open = simple_open, .llseek = generic_file_llseek, }; @@ -257,7 +251,7 @@ static ssize_t tx_queue_status_read(struct file *file, char __user *userbuf, static const struct file_operations tx_queue_status_ops = { .read = tx_queue_status_read, - .open = wl1251_open_file_generic, + .open = simple_open, .llseek = generic_file_llseek, }; -- cgit v1.2.1
