From 55df9f8c24c2ed9c03d5761b45f0916d4bcfc88b Mon Sep 17 00:00:00 2001
From: Natanael Copa <ncopa@alpinelinux.org>

Subject: [PATCH 11/15] df: use f_frsize instead of f_bsize for correct sizes
Use the correct field f_frsize instead of f_bsize.
The statfs f_bsize is the "Optimal transfer block size" while the
f_frsize is the "Fragment size (since Linux 2.6)". On some FUSE
filesystems those may differ.
Fixes bug 9046
