Function Documentation

cache_entry_t* cache_inode_lookupp	(	cache_entry_t *	entry,
		fsal_op_context_t *	context,
		cache_inode_status_t *	status
	)

Public function to look up a directory's parent.

This function looks up (and potentially caches) the parent of a directory.

If a cache entry is returned, its refcount is +1.

Parameters:

[in]	entry	Entry whose parent is to be obtained.
[in]	context	FSAL credentials
[out]	status	Returned status

Returns:

the found entry or NULL on error.

cache_entry_t* cache_inode_lookupp_impl	(	cache_entry_t *	entry,
		fsal_op_context_t *	context,
		cache_inode_status_t *	status
	)

Implements parent lookup functionality.

Looks up (and caches) the parent directory for a directory. If an entry is returned, that entry's refcount is incremented by one. The caller must hold a reference on the entry. It is expected that the caller holds the directory lock on entry. It is also expected that the caller will relinquish the directory lock after return. If result was not cached, the function will drop the read lock and acquire a write lock so it can add the result to the cache.

Parameters:

[in]	entry	Entry whose parent is to be obtained
[in]	context	FSAL operation context
[out]	status	Returned status

Returns:

the found entry or NULL on error.
