cprintf("log_write sector %d\n", b->sector);Build and boot a new kernel and run these three commands at the shell:
echo > a echo x > a rm a mkdir d(Try rm d if you are curious; it should look much the same as rm a.)
You should see a sequence of log_write prints after running each command.
Submit: Record the list and annotate it with the calling function and what block is being written (for example, "file's i-node block", "file's data block", &c).
Hint: an easy way to get the name of the calling function is to add a string argument to log_write, edit all the calls to log_write to pass the name of the calling function, and just print it. You should be able to reason about what kind of block is being written just from the calling function.
You need not write the following up, but try to understand why each write is happening. This will help your understanding of the file system layout and the code.
