Subject: [PATCH RFC] debugfs: rename, export, and use default_open() as debugfs_default_open()
Date: Tue, 20 Mar 2012 15:47:05 -0700 [thread overview]
Message-ID: <201203201547.05656.hartleys@visionengravers.com> (raw)
Rename default_open() in fs/debugfs/file.c to debugfs_default_open()
and export it for use by the many debugfs open() methods that simply
do:
static int foo_open(struct inode *inode, struct file *file)
{
file->private_data = inode->i_private;
return 0;
}
