Please submit a bug report with this message,           the command line used, type of machine and the output of the           compiler when you add -ED -v to the command line. Please also send           us the pre-processed file that is generated by the -ED option (the           file generated is named .i)   1 catastrophic error detected in the compilation of "../../mm/filemap.c". Compilation aborted. cc3089: fatal error: Compilation failed 看看这个函数的代码： /*  * If the page was newly created, increment its refcount and add it to the  * caller's lru-buffering pagevec. This function is specifically for  * generic_file_write().  */ static inline struct page * __grab_cache_page(struct address_space *mapping, unsigned long index,               struct page **cached_page, struct pagevec *lru_pvec) {      int err;      struct page *page; repeat:      page = find_lock_page(mapping, index);      if (!page) {          if (!*cached_page) {               *cached_page = page_cache_alloc(mapping);               if (!*cached_page)                    return NULL;          }          err = add_to_page_cache(*cached_page, mapping,                        index, GFP_KERNEL);          if (err == -EEXIST)               goto repeat;          if (err == 0) {               page = *cached_page;               page_cache_get(page);               if (!pagevec_add(lru_pvec, page))                    __pagevec_lru_add(lru_pvec);               *cached_page = NULL;          }      }      return page; } 有了上次的经验，可以肯定问题发生在               *cached_page = page_cache_alloc(mapping); 将之修改为：               *cached_page = __alloc_pages(mapping_gfp_mask(mapping), 0,                    NODE_DATA(0)->node_zonelists + gfp_zone(mapping_gfp_mask(mapping))); 搞定！
