b1992c37 - kbuild: use $(src) instead of $(srctree)/$(src) for source directory

Sat, 27 Apr 2024 14:55:02 +0000

kbuild: use $(src) instead of $(srctree)/$(src) for source directoryKbuild conventionally uses $(obj)/ for generated files, and $(src)/ forchecked-in source files. It is merely a convention without any functionaldifference. In fact, $(obj) and $(src) are exactly the same, as definedin scripts/Makefile.build: src := $(obj)When the kernel is built in a separate output directory, $(src) doesnot accurately reflect the source directory location. While Kbuildresolves this discrepancy by specifying VPATH=$(srctree) to search forsource files, it does not cover all cases. For example, when adding aheader search path for local headers, -I$(srctree)/$(src) is typicallypassed to the compiler.This introduces inconsistency between upstream and downstream Makefilesbecause $(src) is used instead of $(srctree)/$(src) for the latter.To address this inconsistency, this commit changes the semantics of$(src) so that it always points to the directory in the source tree.Going forward, the variables used in Makefiles will have the followingmeanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source treeConsequently, $(srctree)/$(src) in upstream Makefiles need to be replacedwith $(src).Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier List of files: /linux-6.15/drivers/md/dm-vdo/Makefile

dm vdo: use a proper Makefile for dm-vdoRequires moving dm-vdo-target.c into drivers/md/dm-vdo/This change adds a proper drivers/md/dm-vdo/Makefile and eliminatesthe abnormal use of patsubst in drivers/md/Makefile -- which was thecause of at least one build failure that was reported by the upstreambuild bot.Also, split out VDO's drivers/md/dm-vdo/Kconfig and include it fromdrivers/md/KconfigSigned-off-by: Mike Snitzer Signed-off-by: Matthew Sakai List of files: /linux-6.15/drivers/md/dm-vdo/Makefile
