Hello, Given a file pointer (struct file *), what is the most effecient way to find out the pid of the process that manages this file pointer? I look into the file structure, but still havent seen any way to do that. There is one solution: traverse all the processes in the system, and compare my file pointer with their list of files, but that seems so ineffective, so I dont like that.
