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

2024-05-09T19:34:52+00:00

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for checked-in source files. It is merely a convention without any functional difference. In fact, $(obj) and $(src) are exactly the same, as defined in scripts/Makefile.build: src := $(obj) When the kernel is built in a separate output directory, $(src) does not accurately reflect the source directory location. While Kbuild resolves this discrepancy by specifying VPATH=$(srctree) to search for source files, it does not cover all cases. For example, when adding a header search path for local headers, -I$(srctree)/$(src) is typically passed to the compiler. This introduces inconsistency between upstream and downstream Makefiles because $(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 following meanings: $(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 tree Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced with $(src).

dm vdo: fold thread-cond-var.c into thread-utils

2024-03-01T14:25:54+00:00

Further cleanup is needed for thread-utils interfaces given many functions should return void or be removed entirely because they amount to obfuscation via wrappers. Signed-off-by: Mike Snitzer Signed-off-by: Matthew Sakai

dm vdo: use a proper Makefile for dm-vdo

2024-02-20T18:43:17+00:00

Requires moving dm-vdo-target.c into drivers/md/dm-vdo/ This change adds a proper drivers/md/dm-vdo/Makefile and eliminates the abnormal use of patsubst in drivers/md/Makefile -- which was the cause of at least one build failure that was reported by the upstream build bot. Also, split out VDO's drivers/md/dm-vdo/Kconfig and include it from drivers/md/Kconfig Signed-off-by: Mike Snitzer Signed-off-by: Matthew Sakai
