FreeBSD has no such thing. Do you mean utimensat? utime= nsat is a syscall. The kernel can't call it. All the kernel does it send upcal= ls like FUSE_SETATTR to the fuse server, which in this case is sshfs. If anyt= hing is calling utimensat, it's sftp-server, which is what sshfs invokes on the = ssh server. The platform-specific value of UTIME_OMIT doesn't matter, because sshfs is compiled separately on each platform and any way UTIME_OMIT should never cross the wire over ssh. Instead, the sftp protocol presumably has s= ome other way to convey that meaning. > Linux community too big to report and fix this issue years ago. What do you mean? Are you suggesting that you're unable to report issues t= o a large community, or that because it's a large community, surely this issue must've been fixed on Linux so you aren't going to check? I'm having troub= le following your English. You really should try this on Linux with atime=3Don. I think that by defau= lt Linux sets atime=3Doff, which is probably why you didn't notice the problem there. --=20 You are receiving this mail because: You are the assignee for the bug.=
