From 2cc0fd42f462f3942230c4b33ca2825e2a28765d Mon Sep 17 00:00:00 2001 From: Fabricio Voznika Date: Fri, 24 Apr 2020 11:43:49 -0700 Subject: Fixes for procfs - Return ENOENT for /proc/[pid]/task if task is zoombied or terminated - Allow directory to be Seek() to the end - Construct synthetic files for /proc/[pid]/ns/* - Changed GenericDirectoryFD.Init to not register with FileDescription, otherwise other implementation cannot change behavior.
