| |
Hello all, I have a question with the following kernel code (fs/buffer.c):
block_write_full_page(struct page *page, get_block_t *get_block) { ...... /* OK, are we completely out? */ if (page->index >= end_index+1 || !offset) { UnlockPage(page); return -EIO; } ...... }
If the above code is executed, and it return -EIO, where the kernel will use this return code? and we really arrive here?
thanks.
