... OK so firstly,

boottime is a u64, not a u32. This was already in the changelog... C'mon guys... Pay attention...

then, as described in https://lore.kernel.org/linux-fsdevel/20191225172228.GA13378@avx2/ , You have to use proc_ops in newer kernels instead of file_operations

Proof of concept: use this prepare() of the PKGBUILD:

prepare() {
        true
        #patch -d "${srcdir}/${_pkgname}-${pkgver}" -Np1 -i "${srcdir}"/netatop_kernel_5.5.patch
        sed -i 's/timespec/timespec64/g'  $srcdir/$_pkgname-$pkgver/module/netatop.c
        sed -i 's/getboottime/getboottime64/g' $srcdir/$_pkgname-$pkgver/module/netatop.c
        sed -i 's/file_operations/proc_ops/g' $srcdir/$_pkgname-$pkgver/module/netatop.c
        sed -i 's/\.open/\.proc_open/g' $srcdir/$_pkgname-$pkgver/module/netatop.c
        sed -i 's/\.read/\.proc_read/g' $srcdir/$_pkgname-$pkgver/module/netatop.c
        sed -i 's/\.llseek/\.proc_lseek/g' $srcdir/$_pkgname-$pkgver/module/netatop.c
        sed -i 's/\.release/\.proc_release/g' $srcdir/$_pkgname-$pkgver/module/netatop.c
        sed -i '354d' $srcdir/$_pkgname-$pkgver/module/netatop.c
}

It should work then. I do not get why anyone has noticed this yet, also upstream. They could have already spot this minor problems upstream on RC kernels (yes, that is what they are for). Above all, This fix was very simple...

I've reported to upstream that this no longer compiles under linux kernel version 5.6, but I've no idea whether upstream noticed yet.

Updated to netatop 3.0.

patch needs updating for 5.6+ kernel.

Looking at netatop, v3.0 is out now and available in the AUR. Please, is it possible to update netatop-dkms to v3.0? Thanks a lot in advance.

Package updated. Added patch for kernels >= 5.5 - big thanks to people who did all the research work. LTS kernels are now supported as well.

Patch for kernel>=5.5

git am < <(curl -s http://ix.io/1ovB)

IF the fix applied to netatop (not the dkms) for 5.5 kernels is correct, could you then please apply it to netatop-dkms, too. Thanks a lot.

it seems that, for the 5.5 kernels, the C code has changed somehow. I'm not A C coder, but it seems that the suggestion in the error of the dkms build just works.

dkms install -m netatop -v 2.0 -k 5.5.0-rc7-New #(my test 5.5rc kernel, just like linux-mainline)

---errordump--- /var/lib/dkms/netatop/2.0/build/netatop.c:969:33: error: 'struct task_struct' has no member named 'real_start_time'; did you mean 'start_time'? 969 | tip->btime = div_u64((current->real_start_time + | ^~~~~~~~~~~~~~~ | start_time ---errordump---

Now I just tried what it suggested and it worked:

sed -i 's/real_start_time/start_time/g' /usr/src/netatop-2.0/netatop.c

dkms install -m netatop -v 2.0 -k 5.5.0-rc7-New

Does this make sense what I'm saying? Or did I just get lucky? Hope this helps someone.
