File _service:tar_scm:backport-stat-util-specify-O_DIRECTORY-when-reopening-dir-in-.patch of Package systemd
From e1e32516f98a1f39ce763545de9a8664526d0b8a Mon Sep 17 00:00:00 2001 From: Lennart Poettering <lennart@poettering.net> Date: Thu, 21 Oct 2021 18:07:06 +0200 Subject: [PATCH] stat-util: specify O_DIRECTORY when reopening dir in dir_is_empty_at() That way we can fail earlier if the specified fd is not actually a directory. (Also, it's not exactly according to standards to open things without either O_RDONLY/O_RDWR...)
