Bug Description

Fixed upstream : https://sourceware.org/bugzilla/show_bug.cgi?id=18675

I'm hitting this on Trusty and Xenial with an i386 LXC container on an amd64 kernel hosted on a zfs filesystem.

Calling "fpathconf(my_shiny_fd, _PC_NAME_MAX)" on a filesystem with a large block count results in:

    fstatfs(4, 0xfffdc9f0) = -1 EOVERFLOW (Value too large for defined data type)
