| From | Michel Lespinasse <> | Subject | [PATCH v2 02/35] mmap locking API: mmap_lock_is_contended returns a bool | Date | Fri, 28 Jan 2022 05:09:33 -0800 |
| |
Change mmap_lock_is_contended to return a bool value, rather than an int which the callers are then supposed to interpret as a bool. This is to ensure consistency with other mmap lock API functions (such as the trylock functions).
