f2fs: add NULL pointer check Commit - fa9150a84c - replaces a call to generic_writepages() in f2fs_write_data_pages() with write_cache_pages(), with a function pointer argument pointing to routine: __f2fs_writepage. -> https://git.kernel.org/linus/fa9150a84ca333f68127097c4fa1eda4b3913a22 This patch adds a NULL pointer check in f2fs_write_data_pages() to avoid a possible NULL pointer dereference, in case if - mapping->a_ops->writepage - is NULL.
