This assumes that MAX_INOTIFY_DEV_WATCHERS is an integral multiple
of BITS_PER_LONG, otherwise, the last word will be missing.

Perhaps this would this better be written as:

DECLARE_BITMAP(bitmask, MAX_INOTIFY_DEV_WATCHERS);

and the clearing of it in the original patch:

> + memset(dev->bitmask, 0,
> + sizeof(unsigned long) * MAX_INOTIFY_DEV_WATCHERS / BITS_PER_LONG);

might better be written as:

CLEAR_BITMAP(dev->bitmask, MAX_INOTIFY_DEV_WATCHERS);
