From ca4b8182186b246f925ada5eb22bf49a04249358 Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Mon, 16 May 2022 23:13:05 +0200 Subject: define RLIMIT_RTTIME, bump RLIMIT_NLIMITS This macro exists since Linux 2.6.25 [1] and is defined in glibc since 2.14 [2] for sparc and most supported architectures. RLIMIT_RTTIME has been added later for mips [3] and alpha [4]. For example, RLIMIT_RTTIME is needed to build qemu 7.0.0 with Linux user-land emulation support [5].
