From 576d498e0ac5caff2d9f6312573ab54d98f12d32 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ahelenia=20Ziemia=C5=84ska?= Date: Mon, 3 Jul 2023 16:42:21 +0200 Subject: splice: fsnotify_access(in), fsnotify_modify(out) on success in tee MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Same logic applies here: this can fill up the pipe, and pollers that rely on getting IN_MODIFY notifications never wake up.
