    Uninline find_pid etc set of functions · 8990571e
    Pavel Emelyanov authored
    The find_pid/_vpid/_pid_ns functions are used to find the struct pid by its
    id, depending on whic id - global or virtual - is used.
    
    The find_vpid() is a macro that pushes the current->nsproxy->pid_ns on the
    stack to call another function - find_pid_ns().  It turned out, that this
    dereference together with the push itself cause the kernel text size to
    grow too much.
    
    Move all these out-of-line.  Together with the previous patch this saves a
    bit less that 400 bytes from .text section.
