[ Upstream commit 53e4efa470d5fc6a96662d2d3322cfc925818517 ]
Arnd Bergmann sent a patch to fsdevel, he says:
"orangefs_statfs() copies two consecutive fields of the superblock into the statfs structure, which triggers a warning from the string fortification helpers"
Jan Kara suggested an alternate way to do the patch to make it more readable.
I ran both ideas through xfstests and both seem fine. This patch is based on Jan Kara's suggestion.
