Guenter Roeck eed380f3f5 modpost: Optionally ignore secondary errors seen if a single module build fails ... Commit ea4054a23 (modpost: handle huge numbers of modules) added support for building a large number of modules. Unfortunately, the commit changed the semantics of the makefile: Instead of passing only existing object files to modpost, make now passes all expected object files. If make was started with option -i, this results in a modpost error if a single file failed to build. Example with the current btrfs build falure on m68k: fs/btrfs/btrfs.o: No such file or directory make[1]: [__modpost] Error 1 (ignored) This error is followed by lots of errors such as: m68k-linux-gcc: error: arch/m68k/emu/nfcon.mod.c: No such file or directory m68k-linux-gcc: fatal error: no input files compilation terminated. make[1]: [arch/m68k/emu/nfcon.mod.o] Error 1 (ignored) This doesn't matter much for normal builds, but it is annoying for builds started with "make -i" due to the large number of secondary errors. Those errors unnececessarily clog any error log and make it difficult to find the real errors in the build. Fix the problem by adding a new parameter '-n' to modpost. If this parameter is specified, modpost reports but ignores missing object files. With this patch, error output from above problem is (with make -i): m68k-linux-ld: cannot find fs/btrfs/ioctl.o: No such file or directory make[2]: [fs/btrfs/btrfs.o] Error 1 (ignored) ... fs/btrfs/btrfs.o: No such file or directory (ignored) Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Michael Marek <mmarek@suse.cz> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>		2013-09-23 15:45:03 +09:30
