+ * This function atomically set the COW flag and reset the WRITABLE flag for all PTEs
  * of a remote GPT identified by the <gpt_xp>, <vpn_base>, and <vpn_size arguments.
- * - it set COW and reset WRITABLE when <set_cow> argument is true and PTE is WRITABLE.
- * - it set WRITABLE and reset COW when <set_cow> is false and PTE is COW.
  * It does nothing if the remote PTE is not MAPPED and SMALL.
- * It is called when a fork is executed, or when a COW must be resolved.
