Applications may lock memory that the allocator has already handed out, either by calling mlock() on a returned pointer or via mlockall(MCL_CURRENT). Locking constrains what the kernel permits on the VMA, so quarantine a locked page and then reallocate every slot to confirm the remainder of the pool stays usable. PiperOrigin-RevId: 985384881
