Hi Masahiro, hi Michal, I just got this beatiful warning: hch@carbon:~/work/xfs$ make -j4 SUBDIRS=fs/xfs Makefile:189: ================= WARNING ================ Makefile:190: 'SUBDIRS' will be removed after Linux 5.3 Makefile:191: Please use 'M=' or 'KBUILD_EXTMOD' instead Makefile:192: ========================================== Both the replacement seem to be geared towards building externals modules. But what is the replacement for just building a directory of the normal kernel tree? E.g. what hit this is that I rebased an XFS series, and wanted to compile test just the xfs code for each step using make -j4 SUBDIRS=fs/xfs
