[patch 2/2] fuse: mark pages accessed when written to

[Johannes Weiner]

As fuse does not use the page cache library functions when userspace
writes to a file, it did not benefit from 'c8236db mm: mark page
accessed before we write_end()' that made sure pages are properly
marked accessed when written to.
