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.
