Here is the caller graph for this function:

uint64_t NfsMapsSqlite::GetInode ( const PathString & path )

virtual

Finds the inode for path or issues a new inode.

Implements NfsMaps.

bool NfsMapsSqlite::GetPath	(	const uint64_t	inode,
		PathString *	path
	)

virtual

Finds the path that belongs to an inode. This must be successful. The inode input comes from the file system, i.e. it must have been issued before.

Returns: false if not found

Implements NfsMaps.
