Subject: bpftool: Strip const/volatile/restrict modifiers from .bss and .data vars
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=37f05601eabc29f82c03b461a22d8fafacd736d2;p=linux.git

bpftool: Strip const/volatile/restrict modifiers from .bss and .data vars

Similarly to .rodata, strip any const/volatile/restrict modifiers when
generating BPF skeleton. They are not helpful and actually just get in the way.
