The "d_iname" member was replaced with "d_shortname.string" in the commit referenced in the Fixes tag. This prevented the GDB script "lx-mount" command to properly function:
(gdb) lx-mounts mount super_block devname pathname fstype options 0xff11000002d21180 0xff11000002d24800 rootfs / rootfs rw 0 0 0xff11000002e18a80 0xff11000003713000 /dev/root / ext4 rw,relatime 0 0 Python Exception <class 'gdb.error'>: There is no member named d_iname. Error occurred in Python: There is no member named d_iname.
