)

This function handles memory allocation for a new dentry using the slab allocator.

It also links the dentry to its corresponding VNode (if provided).

Note

This function performs lazy initialization of the dentry slab cache if it does not exist yet.

Parameters

name	The name of the file or directory.
vnode	Pointer to the associated VNode (inode data). Pass NULL if the VNode is not yet available.

Returns

dentry_ptr A pointer to the newly allocated and initialized dentry.
