Hi guys,
I noticed that when I explicitly specify a file and a hardlink to that
file as du's command line arguments it ignores both of them. Here
"kernel", "initramfs" and "System.map" are hardlinks to
kernel-genkernel-x86_64-5.4.2-gentoo,
initramfs-genkernel-x86_64-5.4.2-gentoo and System.map-5.4.10-gentoo-x86_64.

As you can see they are missing from du output:

When I remove the hard link from the arguments the corresponding file
appears in the output:
