[PATCH V2] rtla: Fix Makefile when called from -C tools/

[PATCH V2] rtla: Fix Makefile when called from -C tools/

[Daniel Bristot de Oliveira]

Sedat Dilek reported an error on rtla Makefile when running:

    $ make -C tools/ clean
    [...]
    make[2]: Entering directory
    '/home/dileks/src/linux-kernel/git/tools/tracing/rtla'
    [...]
    '/home/dileks/src/linux-kernel/git/Documentation/tools/rtla'
    /bin/sh: 1: test: rtla-make[2]:: unexpected operator    <------ The problem
    rm: cannot remove '/home/dileks/src/linux-kernel/git': Is a directory
    make[2]: *** [Makefile:120: clean] Error 1
    make[2]: Leaving directory

This occurred because the rtla calls kernel's Makefile to get the
version in silence mode, e.g.,

    $ make -sC ../../.. kernelversion
    5.19.0-rc4

But the -s is being ignored when rtla's makefile is called indirectly,
so the output looks like this:

    $ make -C ../../.. kernelversion
    make: Entering directory '/root/linux'
    5.19.0-rc4
    make: Leaving directory '/root/linux'

Using 'grep -v make' avoids this problem, e.g.,

    $ make -C ../../.. kernelversion | grep -v make
    5.19.0-rc4

Thus, add | grep -v make.

Thanks for v2.
That looks good to me.

Daniel, you are right that not passing -s to make-line will not show
the grep output.

Hi,

what is the status of this patch?

Is it missing some ACKs e.g. from Steven?

Can this go directly to Linus tree as I wanted to see it in Linux v5.19 FINAL?

Thanks.

INFO:

Steven's autoresponder says:

I'm currently traveling and may be slow to respond (and may not at all).
I'll be back at my normal hours on Tuesday, Aug 2nd.

Here the lore-link to v2:

Yes, I'm currently at the SCaLE 19x conference, but I plan on pulling in rtla and rv work while I'm here.
