Subject: [PATCHSET 0/9] perf annotate: More memory footprint reduction
Date: Thu,  4 Apr 2024 10:57:07 -0700

Hello,

This work is continuation of the previous work to reduce the memory
usage in symbol and annotation structures.  Basically I moved some
fields in the annotation which consume spaces in the struct symbol
which is allocated regardless if the symbol has a sample or not when
annotation is enabled.

With this change applied, the struct annotation only has two members -
annotated_source and annotated_branch.  The next step would be to
remove the struct annotation and to have a hash table from symbol to
each annotated struct directly.

No function changes intended.

The code is available at perf/annotate-diet-v3 branch in

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
