Linus Torvalds d9d332e087 anon_vma_prepare: properly lock even newly allocated entries ... The anon_vma code is very subtle, and we end up doing optimistic lookups of anon_vmas under RCU in page_lock_anon_vma() with no locking. Other CPU's can also see the newly allocated entry immediately after we've exposed it by setting "vma->anon_vma" to the new value. We protect against the anon_vma being destroyed by having the SLAB marked as SLAB_DESTROY_BY_RCU, so the RCU lookup can depend on the allocation not being destroyed - but it might still be free'd and re-allocated here to a new vma. As a result, we should not do the anon_vma list ops on a newly allocated vma without proper locking.
