    fs/proc: re-factor proc_pid_cmdline_read() a bit · e4b4e441
    Linus Torvalds authored
    This is a pure refactoring of the function, preparing for some further
    cleanups.  The thing was pretty illegible, and the core functionality
    still is, but now the core loop is a bit more isolated from the thing
    that goes on around it.
    
    This was "inspired" by the confluence of kworker workqueue name cleanups
    by Tejun, currently scheduled for 4.18, and commit 7f7ccc2c
    
     ("proc:
    do not access cmdline nor environ from file-backed areas").
