[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH 0/3] Use g_new() & friends where that makes obvious
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This series only touches allocations with size arguments of the form
sizeof(T). It's mechanical, except for a tiny fix in PATCH 2.
PATCH 1 adds the Coccinelle script.
PATCH 2 cleans up the virtio-9p subsystem, and fixes a harmless typing
error uncovered by the cleanup.
PATCH 3 cleans up everything else. I started to split it up, but
splitting is a lot of decisions, and I just can't see the value.
For instance, MAINTAINERS tells me to split for subsystem "virtio",
patching
hw/char/virtio-serial-bus.c
hw/display/virtio-gpu.c
hw/net/virtio-net.c
hw/virtio/virtio-crypto.c
hw/virtio/virtio-iommu.c
hw/virtio/virtio.c
But it also tells me to split for subsystem "Character devices",
patching
hw/char/parallel.c | 2 +-
hw/char/riscv_htif.c | 2 +-
hw/char/virtio-serial-bus.c | 6 +-
and for subsystem "Network devices", patching
hw/net/virtio-net.c
and for subsystem "virtio-gpu", patching
hw/display/virtio-gpu.c
I guess I'd go with "virtio". Six files down, 103 to go. Thanks, but
no thanks.
Since the transformation is local to a function call, dropping is
completely safe. We can deal with conflicts by dropping conflicting
hunks, with "git-pull -s recursive -X ours". Or drop entire files
with conflicts.
If you want me to split off certain parts, please tell me exactly what
you want split off, and I'll gladly do the splitting. I don't mind
the splitting part, I do mind the *thinking* part.
