Subject: [PATCH v5 0/2] Linux: Fix posix_spawn when user with time namespaces
Date: Mon, 30 May 2022 14:49:16 -0300 [thread overview]
Message-ID: <20220530174918.3056804-1-adhemerval.zanella@linaro.org> (raw)

it simpler than add container support.

helper process.

support: Add support_enter_time_namespace
linux: Add fallback for clone failure on posix_spawn (BZ #29115)
