O que essa saída representa depois de executar cat /proc/vmallocinfo
. Eu sei, isso dá um mapeamento do espaço de endereço virtual do kernel. Mas quero ter uma compreensão profunda.
vmalloc()
? n_tty_open
? Por que existem lacunas entre duas alocações como:
0xffffc90004000000-0xffffc90005001000 16781312 pci_iomap_range+0x66/0x80 phys=e0000000 ioremap
0xffffe8ffffc00000-0xffffe8ffffe00000 2097152 pcpu_get_vm_areas+0x0/0x570 vmalloc
e qualquer outro recurso que possa esclarecer minha dúvida:
