Hi Slava,

> I am slightly confused by comment. Does it mean that the fix introduces more errors? It looks like we need to have more clear explanation of the fix here.

How about below commit msg.

We don't support atime updates of any kind,
because hfs actually does not have atime.

   dirCrDat:      LongInt;    {date and time of creation}
   dirMdDat:      LongInt;    {date and time of last modification}
   dirBkDat:      LongInt;    {date and time of last backup}

   filCrDat:      LongInt;    {date and time of creation}
   filMdDat:      LongInt;    {date and time of last modification}
   filBkDat:      LongInt;    {date and time of last backup}

W/O patch(xfstest generic/003):

 +ERROR: access time has changed for file1 after remount
 +ERROR: access time has changed after modifying file1
 +ERROR: change time has not been updated after changing file1
 +ERROR: access time has changed for file in read-only filesystem

W/ patch(xfstest generic/003):

 +ERROR: access time has not been updated after accessing file1 first time
 +ERROR: access time has not been updated after accessing file2
 +ERROR: access time has changed after modifying file1
 +ERROR: change time has not been updated after changing file1
 +ERROR: access time has not been updated after accessing file3 second time
 +ERROR: access time has not been updated after accessing file3 third time

With this patch, we do not accept changes to atime under any circumstances.
