I have not analyzed it in detail, so no patch for now, but from the git log, I assume c596961d1b4c ("ufs: fix s_size/s_dsize users") caused it.
In ufs_new_fragments() we have this code:
switch (fs32_to_cpu(sb, usb1->fs_optim)) { case UFS_OPTSPACE: request = newcount; if (uspi->s_minfree < 5 || uspi->cs_total.cs_nffree > uspi->s_dsize * uspi->s_minfree / (2 * 100)) break; usb1->fs_optim = cpu_to_fs32(sb, UFS_OPTTIME); break; default: usb1->fs_optim = cpu_to_fs32(sb, UFS_OPTTIME);
case UFS_OPTTIME: request = uspi->s_fpb; if (uspi->cs_total.cs_nffree < uspi->s_dsize * (uspi->s_minfree - 2) / 100) break; usb1->fs_optim = cpu_to_fs32(sb, UFS_OPTTIME); break; }
and as s_dsize is now 64-bit, we get a link error on 32-bit architectures. This may depend on the compiler version in use, as the various built bots gave inconsistent results: On Mark's bot, ARM failed, while for kernelci, ARM and x86 using a gcc-5 build succeeded and MIPS failed with gcc-6.3.
