Subject: [PATCH 17/19] tools: bpf_jit_disasm: make get_last_jit_image return
 unsigned

The function returns always non-negative values.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].

Hi,

To avoid problems with too many mail recipients I have sent whole
patchset only to LKML. Anyway patches have no dependencies.

Regards
Andrzej
