Answer 1

Kernel executes the following steps when we call "open(filepath)":

1. convert the filename to inode.
2. allocate a new file table entry for the inode, initialize various stuff(per process).
3. allocate user file descriptor entry and store into the file table entry(global data structure).
4. return user file descriptor to caller.
