[PATCH v8 21/25] dept: Apply timeout consideration to hashed-waitqueue wait

From: Byungchul Park
Date: Thu Jan 26 2023 - 20:53:13 EST


Now that CONFIG_DEPT_AGGRESSIVE_TIMEOUT_WAIT was introduced, apply the
consideration to hashed-waitqueue wait, assuming an input 'ret' in
___wait_var_event() macro is used as a timeout value.
