I really like this idea.

Consider the following "revision 2" of my proposal:

1) Add a function pointer "current_fs_time" to struct super_block.

2) Replace all calls of the form:

current_fs_time(sb);

with

sb->current_fs_time(sb);

3) Arrange for the default value to point to the current implementation.

These first three could be one patch. They change no functionality;
they just enable the next step.

Finally:

4) Add a mount option to cause sb->current_fs_time(sb) to use the
hi-res implementation.

Comments?
