filp_open - open file and return file pointer

: path to open : open flags as per the open(2) second argument : mode for the new file if O_CREAT is set, else ignored

This is the helper to open a file from kernelspace if you really have to. But in generally you should not do this, so please move along, nothing to see here..

int finish_no_open	(	struct file *	file,
		struct dentry *	dentry
	)

finish_no_open - finish ->atomic_open() without opening the file

: opaque open data : dentry or NULL (as returned from ->lookup())

This can be used to set the result of a successful lookup in ->atomic_open(). The filesystem's atomic_open() method shall return NULL after calling this.

Definition at line 760 of file open.c.

int finish_open	(	struct file *	file,
		struct dentry *	dentry,
		int()(struct inode , struct file *)	open,
		int *	opened
	)

finish_open - finish opening a file : opaque open data : pointer to dentry : open callback

This can be used to finish opening a file passed to i_op->atomic_open().

If the open callback is set to NULL, then the standard f_op->open() filesystem callback is substituted.
