Function Documentation

void nilfs_dirty_inode	(	struct inode *	inode,
		int	flags
	)

nilfs_dirty_inode - reflect changes on given inode to an inode block. : inode of the file to be registered.

nilfs_dirty_inode() loads a inode block containing the specified and copies data from a nilfs_inode to a corresponding inode entry in the inode block. This operation is excluded from the segment construction. This function can be called both as a single operation and as a part of indivisible file operations.

int nilfs_get_block	(	struct inode *	inode,
		sector_t	blkoff,
		struct buffer_head *	bh_result,
		int	create
	)

nilfs_get_block() - get a file block on the filesystem (callback function) - inode struct of the target file - file block number - buffer head to be mapped on - indicate whether allocating the block or not when it has not been allocated yet.

This function does not issue actual read request of the specified data block. It is done by VFS.
