<br>
</span>Yes. hirofumi branch is for kernel. hirofumi-user branch is for userland<br>
commands.<br>

<br>
</span>userland and kernel build sample is here.<br>
<br>
<a href="https://github.com/OGAWAHirofumi/linux-tux3/wiki/Compile" rel="noreferrer" target="_blank">https://github.com/OGAWAHirofumi/linux-tux3/wiki/Compile</a><br>
<br>
But replace "git checkout master" with "git checkout hirofumi". Then<br>
install built kernel from hirofumi branch.<br>
<br>
I guess the kernel tried mount is not match to userland command version.<br>
<br>
If you already installed kernel from hirofumi, can you show dmesg after<br>
trying mount?<br>
