From e8c407717b4814dac5641d93cbbbb9fc394f7cf0 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Wed, 17 Jan 2024 00:57:28 +0000 Subject: io_uring: clean *local_work_add var naming if (!first) { ... } While it reads as do something if it's not the first entry, it does exactly the opposite because "first" here is a pointer to the first entry. Remove the confusion by renaming it into "head".
