From 54aa3de72ea2aaa2e903e7e879a4f3dda515a00e Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Thu, 12 Nov 2020 19:13:37 -0600 Subject: qapi: Use QAPI_LIST_PREPEND() where possible Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).
