Hopefully the final 4 more patches from:
https://lore.kernel.org/lkml/20240202061532.1939474-1-irogers@google.com/
a near half year old adventure in trying to lower perf's dynamic
memory use. These final changes fix reference count issues, some
introduced by making find returned a getted (+1) reference counted
DSO. The last patch lowers the overhead using container_of rather than
a pointer except when reference count checking - asserts maintain the
validity of this.
v5. Rebase, adding use of accessors to dso as necessary. Previous
versions were all rebases or dropping merged patches.
v6. Rebase, move dsos__purge NULL assignment to dso->dsos to above
dso__put to avoid a warning reported by Arnaldo. This was part of
patch 5 in the v5 series.
v7. Rebase dropping 5 merged patches. Break apart the fixes per
file. Tweak to the map dso logic as the else path was missing a
dso__get.
Ian Rogers (4):
perf map: Add missing dso__put in map__new
perf symbol-elf: Ensure dso__put in machine__process_ksymbol_register
perf symbol-elf: dso__load_sym_internal reference count fixes
perf dso: Use container_of to avoid a pointer in dso_data
