    Subjectv2.1.113: loop device oddities
    Hi!

    There may be a fault in the loop device and/or
    the mount/umount stuff.

    I am using kernelv 2.1.113 and mount/unmount v2.8

    The effect: mounting a loop device is ok, umount
    (seems to) work fine. Remounting is also ok, but
    this time the next loop device will be used. umounting
    (seems to work) again. A third remount of the loop device
    fails, cause there could be no free loop device found!!!
    I find no way of getting rid of that mount. I have to
    reboot!!! And more bad: The harddisk device, where the
    corresponding file resides cannot be umounted cleanly due
    to the "hanging" connection to the loop. An fschk-run
    is the result.

    To clearify the situation, I have added the log of the
    mount/umount "session".

    Sometimes I recognize this "hanging" or "not forgetting" of
    previously mounted & later umounted devices also with my
    syquest-EZFlyer drive.

    Fault in the kernel? My fault?

    Any help is welcome! Thank you very much in advance!

    (please cc also to me directly, cause I have again
    problems with the kernel mailing list. Every weekend....)


    KEEP HACKING!
