But the patch is no longer compatible with the latest git, given the recent revert. However, my concern for mem_align still remains. How does the current git use the mem_align parameter in fill_io_buffer(td, b, bs, bs)? Or is it completley handled elsewhere, namely init_io_u() and allocate_io_mem()? When the I/O is normal and uncached won't it all be taken care of in the kernel? -- Sitsofe | http://sucs.org/~sits/ -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
