From: "J. Bruce Fields" <bfields@xxxxxxxxxx>
After commit 95582b008388 "vfs: change inode times to use struct
timespec64" there are spots in the NFSv4 decoding where we decode the
protocol into a struct timeval and then convert that into a timeval64.
That's unnecesary in the NFSv4 case since the on-the-wire protocol also
uses 64-bit values. So just fix up our code to use timeval64 everywhere.
