Quoting Chris Wilson (2017-11-09 10:21:41) > vm_free_page() may call down into set_pages_array_wb() (which itself > sleeps, on x86 at least) but only if on !llc and the caches overflow. > Since this is unlikely, we only rarely trigger the error in practice, > and so to make CI detection of this sleeping bug possible we want to > mark the common vm_free_page() as a potential sleep. >
