Message-ID: <3D81FB0C@zathras> (raw)
Looking at vmalloc implementation, it fills the page table mappings (pgd and
pmd) of only init_mm. When other tasks access these pages their mappings are
updated on demand by the page fault handler, right? Vfree, also, updates the
entries of just init_mm and, of course, flushes the cache and the tlb. But
what about other tasks that have acquired mappings to these pages?
