Struct splinter_event_bus 

Source
#[repr(C)]
pub struct splinter_event_bus { pub dirty_mask: [atomic_uint_least64_t; 16], pub owner_fd: atomic_int_least32_t, pub owner_pid: atomic_int_least32_t, }
Expand description

@brief Event bus for kernel-assisted epoch-change notifications via eventfd.

The owner process calls splinter_event_bus_init() to create an eventfd and record its pid + fd here. Any process (including the owner) can then call splinter_event_bus_open() to obtain a process-local fd to the same kernel object via /proc/<owner_pid>/fd/<owner_fd>.

dirty_mask tracks which slot indices changed since the last read, allowing watchers to enumerate only modified slots instead of scanning the full store. Bits are OR’d in by writers; they are never cleared by the library. For stores with more than SPLINTER_MAX_SLOTS slots, indices are mapped modularly: physical_idx % (SPLINTER_EVENT_BUS_MASK_WORDS * 64).
