Subject: merge-ll: introduce LL_MERGE_OPTIONS_INIT
X-Git-Tag: v2.45.0-rc0~68^2~3
X-Git-Url: http://git.ipfire.org/?p=thirdparty%2Fgit.git;a=commitdiff_plain;h=412aff7b3379b182e3331ec66c0657ae4e39d576

merge-ll: introduce LL_MERGE_OPTIONS_INIT

Introduce a macro to initialize `struct ll_merge_options` in preparation
for the next commit that will add a new member that needs to be
initialized to a non-zero value.
