| |
drivers/md/md.c calls csum_partial().
IF CONFIG_NET=n and BLK_DEV_MD=y, if arch/*/lib/Makefile puts csum-partial.o or checksum.o into lib-y, the function is present. (Of course, if the function is placed in obj-y, there is no problem.)
If CONFIG_NET=n and BLK_DEV_MD=n, if arch/*/lib/Makefile puts csum-partial.o or checksum.o into lib-y, the function is removed from the kernel image due to having no built-in callers.
Build a kernel with CONFIG_NET-n and CONFIG_BLK_DEV_MD=m. Unless csum_partial() is built and kept by some arch Makefile, the result is: ERROR: "csum_partial" [drivers/md/md-mod.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2
Any suggested solutions?
