From 9e8d9e829c2142cf1d7756e9ed2e0b4c7569d84c Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 15 Feb 2021 13:42:18 -0700 Subject: Revert "proc: don't allow async path resolution of /proc/thread-self components" This reverts commit 0d4370cfe36b7f1719123b621a4ec4d9c7a25f89. No longer needed, as the io-wq worker threads have the right identity.
