It says "274 files match" and if I suppress the "--very-quiet" part of
the command, it outputs many files preceded with the word "HANDLING:".

After that, If I try, by example, this command:

/usr/local/bin/spatch -D patch
--cocci-file ./scripts/coccinelle/api/alloc/alloc_cast.cocci
--no-includes --include-headers -I ./arch/x86/include
-I ./arch/x86/include/generated -I ./include -I ./arch/x86/include/uapi
-I ./arch/x86/include/generated/uapi -I ./include/uapi
-I ./include/generated/uapi --include ./include/linux/kconfig.h --jobs 8
--chunksize 1 drivers/staging/qlge/qlge_mpi.c

It says:

HANDLING: drivers/staging/qlge/qlge_mpi.c

But nothing more.

The command Julia suggest has similar results.

Is this correct? I thought it outputs reports or patches.

Thank you,
