Name:Collect processes when the error hit an anonymous page.

Proto:static void collect_procs_anon(struct page *page, struct list_head *to_kill, int force_early)

Type:void

Parameter:

Type	Parameter	Name
struct page *	page
struct list_head *	to_kill
int	force_early

av = Similar to page_get_anon_vma() except it locks the anon_vma.* Its a little more complex as it tries to keep the fast path to a single* atomic op -- the trylock. If we fail the trylock, we fall back to getting a

442

If (av == NULL) Then Return

445

pgoff = Get the offset in PAGE_SIZE.* (TODO: hugepage should have ->index in PAGE_SIZE)

446

read_lock( & tasklist_lock)

449

t = Determine whether a given process is "early kill" process which expects* to be signaled when some page under the process is hwpoisoned.* Return task_struct of the dedicated thread (main thread unless explicitly

451

If Not t Then Continue

455

vma = vma

456

If Not page_mapped_in_vma - check whether a page is really mapped in a VMA*@page: the page to test*@vma: the VMA to test* Returns 1 if the page is mapped into the page tables of the VMA, 0* if the page is not mapped into the page tables of this VMA. Only Then Continue

458

If The address space we belong to. == mm Then Schedule a process for later kill.* Uses GFP_ATOMIC allocations to avoid potential recursions in the VM.
