Subject: next-20210511 - btrfs build failure on arm
Date: Tue, 11 May 2021 14:08:02 -0400	[thread overview]
Message-ID: <564681.1620756482@turing-police> (raw)

An arm allmodconfig build died with:

ERROR: modpost: "__aeabi_uldivmod" [fs/btrfs/btrfs.ko] undefined!

Some digging around with nm and looking at the assembler points at:

@ /usr/src/linux-next/fs/btrfs/extent_io.c:2676:        const int nr_bits = (end + 1 - start) / fs_info->sectorsize_bits;
        adds    r1, r1, #1      @, tmp552, 
        adc     r0, r0, #0      @, tmp551, 
        ldr     r3, [r5, #1576] @ tmp2, _47->sectorsize_bits
        bl      __aeabi_uldivmod                @       

Introduced by this commit:

    btrfs: submit read time repair only for each corrupted sector

Looks like that line could use something from include/linux/math.h
