From 523d2b060f9d7cf340baa0615443e3fae7f25555 Mon Sep 17 00:00:00 2001 From: Matt Madison <matt@madison.systems> Date: Sun, 11 Apr 2021 06:48:54 -0700 Subject: [PATCH] Replace stat/fstat calls with __xstat/__fxstat The stat-family syscalls were reworked in glibc 2.33, so make the libv4lconvert plugin compatible with the older glibc used in L4T containers.
