[PATCH v7 0/3] rust: Add local_irq abstraction, SpinLockIrq
Posted by Lyude Paul 1 month, 1 week ago
This adds a token for annotating contexts where IRQs may be disabled on
non-PREEMPT_RT kernels, a way to use these tokens with Lock types, and
introduces bindings for spin_lock_irqsave() and
spin_unlock_irqrestore().

This patch series depends on the NotThreadSafe type from Alice:

(Please re-review, since there's been some changes here!)

Lyude Paul (3):
  rust: Introduce local_irq module
  rust: sync: Introduce lock::Backend::Context and
    lock::BackendWithContext
  rust: sync: Add SpinLockIrq

Ignore this, sorry! I went back to my editor and realized a change made it
into this series that shouldn't have.  Will send a respin in a moment
