  • 895af77fe6 check blockno passed to idestart Frans Kaashoek 2015-04-10 07:15:06 -04:00
  • c24ac5d763 Disentangle block size from the disk's sector size. Set block size to 1024 to show that they can be different. Clean up mkfs, simplifying specifying fs parameters, remove some redundancy between fs and mkfs, and fix disk layout bugs. Call blocks in the file system blocks instead of sectors. Passes usertests for different block sizes. Frans Kaashoek 2015-04-03 08:22:02 -04:00
