Hi Pankaj! > - /* Size must be multiple of hard sectorsize */ > + /* Size must be multiple of logical block size */ > if (unlikely(size & (bdev_logical_block_size(bdev)-1) || > (size < 512 || size > PAGE_SIZE))) { > printk(KERN_ERR "getblk(): invalid block size %d requested\n", OK with me. However, maybe that comment should just go away? The code on the following line articulates the constraint very clearly. If you tweak things, please fix the spacing for "(bdev)-1".
