Revision 4983da07f1e2e8dc81cb9d640fbf35b899cdbdf2 authored by Christoph Lameter on 15 March 2006, 03:50:19 UTC, committed by Linus Torvalds on 15 March 2006, 05:43:02 UTC
page migration currently simply retries a couple of times if try_to_unmap() fails without inspecting the return code. However, SWAP_FAIL indicates that the page is in a vma that has the VM_LOCKED flag set (if ignore_refs ==1). We can check for that return code and avoid retrying the migration. migrate_page_remove_references() now needs to return a reason why the failure occured. So switch migrate_page_remove_references to use -Exx style error messages.
