A few kernel modules have source files in multiple subdirectories. Trying to build just a single object of a source file in such a subdirectory currently doesn't work. For example: hch@brick:~/work/xfs$ make fs/xfs/libxfs/xfs_alloc.o CALL scripts/checksyscalls.sh CALL scripts/atomic/check-atomics.sh DESCEND objtool scripts/Makefile.build:42: fs/xfs/libxfs/Makefile: No such file or directory make[1]: *** No rule to make target 'fs/xfs/libxfs/Makefile'. Stop. make: *** [Makefile:1747: fs/xfs/libxfs/xfs_alloc.o] Error 2 Is there any reasonably easy way to get this to work?
