Marcello,

Attached is a patch which fixes some compiler warnings in mmigrate.c
that I was getting with the migration cache code.  The only substantive
change was to change:

         /* Wait for all operations against the page to finish. */
         ret = migrate_fn(page, newpage, &vlist);
         switch (ret) {
         default:
                 /* The page is busy. Try it later. */
                 goto out_busy;
         case -ENOENT:
                 /* The file the page belongs to has been truncated. */
                 page_cache_get(page);
                 page_cache_release(newpage);
                 newpage->mapping = NULL;
                 /* fall thru */
         case 0:
                 /* fall thru */
         }

in generic_migrate_page(), to:

         /* Wait for all operations against the page to finish. */
         ret = migrate_fn(page, newpage, &vlist);
         switch (ret) {
         case -ENOENT:
                 /* The file the page belongs to has been truncated. */
                 page_cache_get(page);
                 page_cache_release(newpage);
                 newpage->mapping = NULL;
                 /* fall thru */
         case 0:
                 break;
         default:
                 /* The page is busy. Try it later. */
                 goto out_busy;
         }

This change was made to get rid of the warning:

mm/mmigrate.c:500: warning: deprecated use of label at end of compound statement

I suppose you used the previous order to eliminate an extra branch or
some such.  Do you have any other suggestion on how to eliminate that
warning?
