This is a note to let you know that I've just added the patch titled selftests: find echo binary to use -ne options to the 6.2-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: selftests-find-echo-binary-to-use-ne-options.patch and it can be found in the queue-6.2 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ae4856791306b20082c52da09d1df0a6b135ec3a Author: Guillaume Tucker <guillaume.tucker@xxxxxxxxxxxxx> Date: Fri Feb 3 16:26:03 2023 +0100 selftests: find echo binary to use -ne options [ Upstream commit 4ebe33398c40c1118b4d8546978036c0e0032d1b ] Find the actual echo binary using $(which echo) and use it for formatted output with -ne. On some systems, the default echo command doesn't handle the -e option and the output looks like this (arm64 build): -ne Emit Tests for alsa -ne Emit Tests for amd-pstate -ne Emit Tests for arm64 This is for example the case with the KernelCI Docker images e.g. kernelci/gcc-10:x86-kselftest-kernelci. With the actual echo binary (e.g. in /bin/echo), the output is formatted as expected (x86 build this time): Emit Tests for alsa Emit Tests for amd-pstate Skipping non-existent dir: arm64 Only the install target is using "echo -ne" so keep the $ECHO variable local to it.
