From 6baf9e67c9c5d738188b8490893c7e079d3deb7e Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 5 Jan 2018 05:19:56 +0100 Subject: irq/work: Improve the flag definitions IRQ_WORK_FLAGS is defined simply to 3UL. This is confusing as it says nothing about its purpose. Define IRQ_WORK_FLAGS as a bitwise OR of IRQ_WORK_PENDING and IRQ_WORK_BUSY and change its name to IRQ_WORK_CLAIMED. While we're at it: use the BIT() macro for all flags.
