Let's use bitfields for our booleans, and don't try to apply binary OR or addition on them, because that's weird and we
should instead use logical OR only.
struct Window {
MMapCache *cache;
- bool invalidated;
- bool keep_always;
- bool in_unused;
+ bool invalidated:1;
+ bool keep_always:1;
+ bool in_unused:1;
int prot;
void *ptr;
unsigned n_hit, n_missed;
-
Hashmap *fds;
Context *contexts[MMAP_CACHE_MAX_CONTEXTS];
if (c->window->fd->sigbus)
return -EIO;
- c->window->keep_always |= keep_always;
+ c->window->keep_always = c->window->keep_always || keep_always;
*ret = (uint8_t*) c->window->ptr + (offset - c->window->offset);
return 1;
return -ENOMEM;
context_attach_window(c, w);
- w->keep_always += keep_always;
+ w->keep_always = w->keep_always || keep_always;
*ret = (uint8_t*) w->ptr + (offset - w->offset);
return 1;
