Arch doesn't ship the entire built kernel tree, just headers. Is there a way to compile this without it compiling the entire kernel?

[parkerlreed]

Trying this on Ubuntu it prints some messages about what has to be done

Same here! This is what happens on Fedora 32:

The following works for kernel 5.6.6 on fedora 32:

make -C /lib/modules/`uname -r`/build  M=`pwd` SRCROOT=`pwd` modules

[aenertia]

I get unknown symbols when compiling with that on fc32:

[olinorwell]

The following works for kernel 5.6.6 on fedora 32:

make -C /lib/modules/`uname -r`/build  M=`pwd` SRCROOT=`pwd` modules

This worked for me on Arch too after I ran: sudo pacman -S linux-headers

[BOFH2k]

See insmod sequence in #7 for fix.

Anyone else seeing error: redefinition of 'struct request'?

I get that error for both this fork and @grandchild's.

[Jenni32222]

Same error as above, has anyone found a fix after all this time?
