FlockMode

ktstr::flock

Enum FlockMode 

Source 
pub enum FlockMode {
    Exclusive,
    Shared,
}
Expand description

Requested sharing mode for try_flock. Translated to the corresponding non-blocking [rustix::fs::FlockOperation] internally; callers never see the libc-specific constants.

Shared between LLC + per-CPU flocks (vmm::host_topology) and cache-entry flocks (cache). A single type prevents three-enum drift — earlier revisions had FlockMode + FlockKind + LlcLockMode with identical shape. LlcLockMode remains distinct as the scheduler-intent layer (perf-mode vs. no-perf-mode request), not a flock operation.

Variants§

§

Exclusive

Exclusive (LOCK_EX) — sole access to the lock file.

§

Shared

Shared (LOCK_SH) — multiple holders can coexist.
