From ce92834407a465c25c0be1a4a0339c625e44c4db Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 29 Jul 2016 11:54:35 -0300 Subject: [PATCH] perf target: str_error_r() always returns the buffer it receives So no need for checking if it uses the strerror_r() GNU variant error reporting mechanism, i.e. if it returns a pointer to a immutable string internal to glibc.
