    SubjectGigantic memory leak in linux-2.6.[789]!
    Hi all!

    After some more testing after the previous post of the OOPS in
    generic_delete_inode, we have now found a gigantic memory leak in Linux 2.6.
    [789]. The scenario is the same:

    File system: EXT3
    Unpack and delete linux- with this Bash while loop:

    let "i = 0"
    while [ "$i" -lt 10 ]; do
    tar jxf linux-;
    rm -fr linux-;
    let "i = i + 1"

    When the loop has completed, the system use 124 MB memory more _each_ time....
    so it is pretty easy to make a denial-of-service attack :-(

    We have tried the same test on a RHEL WS 3 host (running a RedHat 2.4 kernel)
    - and there is no problem.

    Any deas?
