5fcbd555 - iomap: split bios to zone append limits in the submission handlers

Thu, 06 Feb 2025 06:40:02 +0000

iomap: split bios to zone append limits in the submission handlersProvide helpers for file systems to split bios in the direct I/O andwriteback I/O submission handlers. The split ioends are chained tothe parent ioend so that only the parent ioend originally generatedby the iomap layer will be processed after all the chained off childrenhave completed. This is based on the block layer bio chaining that hassupported a similar mechanism for a long time.This Follows btrfs' lead and don't try to build bios to hardware limitsfor zone append commands, but instead build them as normal unconstrainedbios and split them to the hardware limits in the I/O submission handler.Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20250206064035.2323428-5-hch@lst.deReviewed-by: "Darrick J.

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/fs/iomap/Makefile
