From 70b9c8563c9c29102a785d4822f0d77d33fee808 Mon Sep 17 00:00:00 2001 From: Alice Ryhl Date: Fri, 7 Mar 2025 15:26:59 -0800 Subject: rust: sync: condvar: Add wait_interruptible_freezable() To support waiting for a `CondVar` as a freezable process, add a wait_interruptible_freezable() function. Binder needs this function in the appropriate places to freeze a process where some of its threads are blocked on the Binder driver.
