Subject: sparse: Fix an "symbol 'merge_file' not decared" warning
X-Git-Tag: v1.7.6-rc0~147^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1e0f8c41ac157c54a33f2ee0afb7d96f5156ed0d;p=git.git

sparse: Fix an "symbol 'merge_file' not decared" warning

In order to fix the warning, we add a new "merge-file.h" header
containing the extern declaration of the merge_file() function,
and include the header in the source files that require the
declaration.
