Subject: [iproute PATCH v5 2/5] Use C99 style initializers everywhere
This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).
Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.
The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.
Signed-off-by: Phil Sutter <phil@....cc>
---
Changes since v4:
- Rebased to current origin/master, minor context conflict in
ip/iplink.c.
Changes since v3:
- Use empty instead of zero initializer.
Changes since v2:
- Flatten initializers.
- Leave a final comma in place.
- Fix checkpatch warnings.
- Initialize nlmsg_seq in the declaration, too.
- Use C99-style init in tc_bpf.c to get rid of the memset().
Changes since v1:
- Dropped former changes to tc/tc_bpf.c as they are incompatible to older
gcc versions (at least <=3.4.6).
