Not sure what happened this time, but I got
drivers/md/.dm-round-robin.mod.o.cmd:5: *** unterminated call to
function 'wildcard': missing ')'. Stop.
The depfile is indeed corrupt (truncated):
tail drivers/md/.dm-round-robin.mod.o.cmd
arch/x86/include/asm/disabled-features.h \
$(wildcard include/config/x86/intel/mpx.h) \
arch/x86/include/asm/rmwcc.h \
arch/x86/include/asm/barrier.h \
$(wildcard include/config/x86/ppro/fence.h) \
arch/x86/include/asm/nops.h \
$(wildcard include/config/mk7.h) \
include/asm-generic/barrier.h \
include/asm-generic/bitops/find.h \
$(wildcard include/config/generic/
The file is exactly 8kB long:
$ ls -l drivers/md/.dm-round-robin.mod.o.cmd
