From bdba53687e450dcbae614ba06d0bc8be5e4e34c5 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 5 Jun 2019 14:17:42 -0400 Subject: nfsd: use 64-bit seconds fields in nfsd v4 code 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. Signed-off-by: J.
