Function Documentation

cache_entry_t* cache_inode_lookup	(	cache_entry_t *	parent,
		fsal_name_t *	name,
		fsal_attrib_list_t *	attr,
		fsal_op_context_t *	context,
		cache_inode_status_t *	status
	)

Public function for looking up a name in a directory.

Looks up for a name in a directory indicated by a cached entry. The directory should have been cached before.

If a cache entry is returned, the refcount on entry is +1.

Parameters:

[in]	parent	Entry for the parent directory to be managed.
[in]	name	Name of the entry that we are looking up.
[out]	attr	Attributes of the found entry.
[in]	context	FSAL credentials
[out]	pstatus	Returned status

Returns:

The found entry or NUL.

cache_entry_t* cache_inode_lookup_impl	(	cache_entry_t *	parent,
		fsal_name_t *	name,
		fsal_op_context_t *	context,
		cache_inode_status_t *	status
	)

Do the work of looking up a name in a directory.

This function looks up a filename in the given directory. It implements the functionality of cache_inode_lookup and expects the directory to be read-locked when it is called. If a lookup from cache fails, it will drop the read lock and acquire a write lock before proceeding. The caller is responsible for freeing the lock on the directory in any case.

If a cache entry is returned, its refcount is incremented by 1.

Parameters:

[in]	parent	The directory to search
[in]	name	The name to be looked up
[in]	context	FSAL credentials
[out]	status	Returned status

Returns:

The cache entry corresponding to name or NULL on error.
