From f979c20547e72568e3c793bc92c7522bc3166246 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Fri, 9 May 2025 12:12:47 +0100 Subject: [PATCH] io_uring: account drain memory to cgroup Account drain allocations against memcg. It's not a big problem as each such allocation is paired with a request, which is accounted, but it's nicer to follow the limits more closely.
