From d4b29ddf82a458935f1bd4909b8a7a13df9d3bdc Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Tue, 17 Jun 2025 23:41:55 +0900 Subject: rust: time: Add wrapper for fsleep() function Add a wrapper for fsleep(), flexible sleep functions in include/linux/delay.h which typically deals with hardware delays. The kernel supports several sleep functions to handle various lengths of delay. This adds fsleep(), automatically chooses the best sleep method based on a duration. fsleep() can only be used in a nonatomic context. This requirement is not checked by these abstractions, but it is intended that klint [1] or a similar tool will be used to check it in the future.
