Agreed.

Indeed this does not work. It requires some changes to Makefiles to see
that it does not work, as this assertion is only used when a filter is
passed (which current cmd_clang_tools cannot do).
What would you recommend to fix that? If we take the first entry:
{
"command": "clang ...",
"directory": "/tmp/foo",
"file": "/ABSOLUTE/PATH/linux-clang-tidy/arch/mips/crypto/crc32-mips.c"
},
I don't see an easy way to know that "/ABSOLUTE/PATH/linux-clang-tidy/"
should be removed. We could probably compute it from the command value
but that isn't a great way forward.
There are some entries that look like this. Those are easy to deal with.
{
"command": "clang ...",
"directory": "/tmp/foo",
"file": "/tmp/foo/drivers/tty/vt/defkeymap.c"
}
