NAME
       try_to_release_page - release old fs-specific metadata on a page


SYNOPSIS
       int try_to_release_page  (struct page * page, gfp_t gfp_mask);


ARGUMENTS
       page   the page which the kernel is trying to free

       gfp_mask
              memory allocation flags (and I/O mode)


DESCRIPTION
       The  address_space  is  to  try  to  release  any data against the page
       (presumably at page->private). If the release  was  successful,  return
       ‘1’. Otherwise return zero.

       The gfp_mask argument specifies whether I/O may be performed to release
       this page (__GFP_IO), and whether the call may block (__GFP_WAIT).
