I noticed that the commit below regressed cifs/smb3 xfstest 258 on 5.4-rc1 and later. "Testing for negative seconds since epoch" "Timestamp wrapped" .... Did xfstest 258 get updated to account for the new behavior with this patch? commit cb7a69e605908c34aad47644afeb26a765ade8d7 Author: Deepa Dinamani <deepa.kernel@xxxxxxxxx> Date: Fri Mar 22 14:32:35 2019 -0700 fs: cifs: Initialize filesystem timestamp ranges Fill in the appropriate limits to avoid inconsistencies in the vfs cached inode times when timestamps are outside the permitted range. Also fixed cnvrtDosUnixTm calculations to avoid int overflow while computing maximum date. -- Thanks, Steve
