simple_open: automatically convert to simple_open()

2012-04-05T22:25:50Z

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

usb: remove bad dput after dentry_unhash

2011-06-03T22:43:00Z

Commit 64252c75a removed the useless dget from dentry_unhash but didn't fix up this caller in the usb code. There used to be exactly one dput per dentry_unhash call; now there are none. Tested-by: Sebastian Andrzej Siewior Signed-off-by: Sage Weil Signed-off-by: Al Viro
