Tiwei Bie dd072fa647 um: vector: Reduce stack usage in vector_eth_configure() ... [ Upstream commit 2d65fc13be ] When compiling with clang (19.1.7), initializing *vp using a compound literal may result in excessive stack usage. Fix it by initializing the required fields of *vp individually. Without this patch: $ objdump -d arch/um/drivers/vector_kern.o | ./scripts/checkstack.pl x86_64 0 ... 0x0000000000000540 vector_eth_configure [vector_kern.o]:1472 ... With this patch: $ objdump -d arch/um/drivers/vector_kern.o | ./scripts/checkstack.pl x86_64 0 ... 0x0000000000000540 vector_eth_configure [vector_kern.o]:208 ...
