Comment 6 for bug 1883343

So what is `.`?

Searching for all files named unistd.h, I think it's one of the following 2 (note that both files are identical according to diff):

/usr/src/linux-raspi-headers-5.4.0-1012/arch/arm64/include/asm/unistd.h
/usr/src/linux-raspi-headers-5.4.0-1008/arch/arm64/include/asm/unistd.h

Full find command output at https://gist.github.com/nyanpasu64/53d1341655d4d63fd61e7d0a9de8313e.

I think that systemtap ships with a unistd stub at /usr/share/systemtap/runtime/linux/compat_unistd.h which has conflicts with the real unistd.h.
