Please do not reopen the bug.

So what?  You aren't using a 2012 build of sshfs, I hope.

> This change nothing.

It changes everything.  Without "-o strictatime", Linux does "relatime", which
basically means that it only updates atime once every 24 hours.  You MUST use
"-o nostrictatime" to see the POSIX-compliant atime behavior.

> Do you test all fusefs consumers to ensure that updating only atime work correctly?

All?  Of course not.  But I have tested several, and they all work fine.

Please do not reopen the bug.
