[Bug 1522974] [NEW] fpathconf(_PC_NAME_MAX) fails against large filesystems for 32bit processes

[Michael Jeanson]

Public bug reported:

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)

** Affects: glibc (Ubuntu)
     Importance: Undecided
         Status: New
