No, it's not the correct fix. You shouldn't need to do the GETATTR first,
and doing a SETATTR will cause a synchronous update of the atime, which is
not what you want. This also doesn't fix that standard case of open/mmap() not
updating the access time, which is the real problem, not execve.
Guessing, I think the correct fix is probably to set the IN_ACCESS flag in
ufs_open() [and similarly with other filesystems where this makes sense] if
the filesystem is not mounted with the noatime flag. However, I'm not sure
of the symantics of the access time in the relavent standards, and I seem
to recall Bruce saying that it was incorrect to indicate an access on just
an open(), but I may be mistaken.
