int nilfs_ifile_create_inode	(	struct inode *	ifile,
		ino_t *	out_ino,
		struct buffer_head **	out_bh
	)

nilfs_ifile_create_inode - create a new disk inode : ifile inode : pointer to a variable to store inode number : buffer_head contains newly allocated disk inode

Return Value: On success, 0 is returned and the newly allocated inode number is stored in the place pointed by , and buffer_head pointer that contains newly allocated disk inode structure is stored in the place pointed by On error, one of the following negative error codes is returned.

%-EIO - I/O error.

%-ENOMEM - Insufficient amount of memory available.

%-ENOSPC - No inode left.

int nilfs_ifile_delete_inode	(	struct inode *	ifile,
		ino_t	ino
	)

nilfs_ifile_delete_inode - delete a disk inode : ifile inode : inode number

Return Value: On success, 0 is returned. On error, one of the following negative error codes is returned.

%-EIO - I/O error.

%-ENOMEM - Insufficient amount of memory available.

%-ENOENT - The inode number have not been allocated.
