      The 'PG_checked' flag is used to indicate that the page does not
      supposedly exist on the media (e.g., a hole or a page beyond the
      inode size), so it requires slightly bigger budget, because we have
      to account the indexing size increase. And this flag basically
      tells that the budget for this page has to be "new page budget".
      The "new page budget" is slightly bigger than the "existing page
      budget".
      
      The 'do_readpage()' function has the following assertion which
      sometimes is hit: 'ubifs_assert(!PageChecked(page))'. Obviously,
      the meaning of this assertion is: "I should not be asked to read
      a page which does not exist on the media".
      
      However, in 'ubifs_write_begin()' we have a small "trick". Notice,
      that VFS may write pages which were not read yet, so the page data
      were not loaded from the media to the page cache yet. If VFS tells
      that it is going to change only some part of the page, we obviously
      have to load it from the media. However, if VFS tells that it is
      going to change whole page, we do not read it from the media for
      optimization purposes.
      
      However, since we do not read it, we do not know if it exists on
      the media or not (a hole, etc). So we set the 'PG_checked' flag
      to this page to force bigger budget, just in case.
      
      So 'ubifs_write_begin()' sets 'PG_checked'. Then we are in
      'ubifs_write_end()'. And VFS tells us: "hey, for some reasons I
      changed my mind and did not change whole page". Frankly, I do not
      know why this happens, but I hit this somehow on an ARM platform.
      And this is extremely rare.
      
      So in this case UBIFS does the following:
      
      1. Cancels allocated budget.
      2. Loads the page from the media by calling 'do_readpage()'.
      3. Asks VFS to repeat the whole write operation from the very
         beginning (call '->write_begin() again, etc).
      
      And the assertion warning is hit at the step 2 - remember we have
      the 'PG_checked' set for this page, and 'do_readpage()' does not
      like this. So this patch fixes the problem by adding step 1.5 and
      cleaning the 'PG_checked' before calling 'do_readpage()'.
      
      All in all, this patch does not fix any functionality issue, but it
      silences UBIFS false positive warning which may happen in very very
      rare cases.
      
      And while on it, this patch also improves a commentary which explains
      the reasons of setting the 'PG_checked' flag for the page. The old
      commentary was a bit difficult to understand.

      Simplify UBIFS configuration menu and kill the option to enable self-check

      using the module parameters or the corresponding sysfs interfaces. And
      there is a value in simplifying the kernel configuration menu which becomes
      increasingly large.
