This patch adds a new command line option -E to modpost, expecting a symbol file as an argument which is read prior to symbol processing. -E can be supplied multiple times for as many files as is needed. When building kernel modules that depend on other modules not in the main kernel tree, modpost complains about undefined symbols: # make -C /path/to/linux/kernel M=/path/to/my/module ... Building modules, stage 2. .... WARNING: "rt_copy_buf" [/home/rich/osc_etl_rtw/osc_kmod.ko] undefined! ...etc This situation occurs when modpost processes the new module's symbols. When it finds symbols not exported by the mainline kernel, it issues this warning. The patch adds a new command line option -e to modpost which expects a symbol file as an argument. The symbols listed in this file are added to modpost's symbol tables during startup. -e can be supplied as often as required. This patch works together with the second patch. It introduces a new make variable, KBUILD_EXTRA_SYMBOLS, which is used when calling modpost. Signed-off-by: Richard Hacker <lerichi@gmx.net> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> |
