I just noticed that rule_ld_ko_o produces verbose output when linking
modules:
% make
...
echo ' LD [M] drivers/ata/ata_generic.ko'; ld -r -m elf_x86_64 -z max-page-size=0x200000 -T ./scripts/module-common.lds --build-id -o drivers/ata/ata_generic.ko drivers/ata/ata_generic.o drivers/ata/ata_generic.mod.o ; true ; printf '%s\n' 'cmd_drivers/ata/ata_generic.ko := ld -r -m elf_x86_64 -z max-page-size=0x200000 -T ./scripts/module-common.lds --build-id -o drivers/ata/ata_generic.ko drivers/ata/ata_generic.o drivers/ata/ata_generic.mod.o ; true' > drivers/ata/.ata_generic.ko.cmd ;
LD [M] drivers/ata/ata_generic.ko
so I think we need to use the $(Q) macro to respect the KBUILD_VERBOSE
and V kbuild settings.
Masahiro, does something like this look correct?
Thanks,

Subject: [PATCH] [squash] modpost: fix rule_ld_ko_o verbosity
Note: squash with ("modpost: Integrate klp-convert")
rule_ld_ko_o should include $(Q) to honor build verbosity setting.
Cargo-cult-stolen from 70923bd26c73 ("perf tools: Make flex/bison calls
honour V=1").
