Description of problem:
When the file is created, the atime is lower than ctime or mtime. When the file is accessed using cat, the atime does not get updated.
Also the option strictatime is not effective (the atime updates the same way as with standard relatime).
This issue was found with the help of xfstests (test no. 192).

Version-Release number of selected component (if applicable):
kernel-2.6.32-119.el6

How reproducible:
Fairly often but not 100 %, don't forget to remove file that you are going to test the atime with and wait for a while before the test.

Steps to Reproduce:
1. mount nfs share (I used localhost nfs server)
2. cd to the mounted share
3. echo test >file;stat file;sleep 40;cat file;stat file
  
Actual results:
atime is lowest of the three at first stat and remains that way even after the cat.

Expected results:
The access time is updated after the cat.
