Has this been resolved in the meantime?
Not that I'm aware of.
I'm running into a little dilemma when working on yet another spin on
the RDB partition patch (the patch that just won't die): either use old
gcc 4.6.3, and lack __udivdi3 support, or new and shiny 8.10 with its
strncmp mess.
You're not supposed to do 64-bit divisions in the kernel, except using
do_div() and the other helpers in include/linux/math64.h and
include/asm-generic/div64.h.
It's not just me - this happens when building without LBD support:
ERROR: "__udivdi3" [drivers/md/dm-thin-pool.ko] undefined!
Looks like DM_THIN_PROVISIONING should depend on LBD support being
enabled...
This is with gcc 8.10 from kernel.org, FWIW.
Cheers,
Michael
