    SubjectRe: [PATCH 0/3] extend get/setrlimit to support setting rlimits external to a process (v5)
    Ok, Sorry for the delay, I had several other items that I needed to finish.
    Version 5 of this patch set taking Marcins notes into account

    Change Notes:

    1) Fixed up various buffer leaks, sizings, and other misc. items that Marcin
    pointed out in his last post to this thread

    2) Added documentation in Documentation/filesystems/proc.txt so that users
    would have a better idea about how to use the proc interface here (I figured
    that the syscall interface would be rather self explanitory and get augmented
    into the man pages soon enough)



    Its been requested often that we have the ability to read and modify process
    rlimit values from contexts external to the owning process. Ideally this allows
    sysadmins to adjust rlimits on long running processes wihout the need to stop
    and restart those processes, which incurs undesireable downtime. This patch
    enables that functionality, It does so in two places. First it enables process
    limit setting by writing to the /proc/pid/limits file a string in the format:
    <limit> <current limit> <max limit> > /proc/<pid>/limits
    where limit is one of

    Secondly it allows for programatic setting of these limits via 2 new syscalls,
    getprlimit, and setprlimit, which act in an identical fashion to getrlimit and
    setrlimit respectively, except that they except a process id as an extra
    argument, to specify the process id of the rlimit values that you wish to
