checkpatch.pl getting stuck on a macro in mm/kmsan/kmsan_test.c

[Lukas Bulwahn <lukas.bulwahn@xxxxxxxxx>]

Dear Joe,

while running checkpatch.pl -f on all files in the kernel repository
(v6.8-rc1) for some experiment, I noticed that checkpatch.pl got stuck
on mm/kmsan/kmsan_test.c, i.e., ./scripts/checkpatch.pl -f
mm/kmsan/kmsan_test.c never terminates.

I could already boil it down to checkpatch getting stuck on the macro
#define DEFINE_TEST_MEMSETXX(size), see lines 541 to 554 in
mm/kmsan/kmsan_test.c on v6.8-rc1.

I do not know if it is worth fixing, but certainly I was surprised
that reasonable code can put checkpatch into some stuck state.

Best regards,

Lukas
