Corrections and clarifications for project #4

  • Please do an svn update after 10:30 AM on 4/18/14. There was a small error in cfs.h in the padding size for the inode.
  • The project handout ommited the Sync system call (it is mentioned in the handout, but not in the list of required system calls). You do need to impelement this call. Upon return, all data should be flushed to disk (if you are doing the version with the buffer cache, you will need to make sure the buffer cache is flushed too).
  • You must submit your program using the make submit rule in build. You can not use the web interface to submit for this project.
  • The return value for sucess of Read_Entry is 0, not 1.
