Ending SCSI request in block level driver
hi,

We are currently working on block level driver in linux ubuntu .we are having a storage controller and we are trying to capture and filling the scsi requests to a particular LUN.

We are trying to mask a request for that LUN. We were able to get LUN id of hard drive. Our objective is to restrict all the request for that particular LUN at the block level.

We tried to end the request using blk_end_request/blk_end_request_all when the request is to the LUN id that we are trying to mask ,
but while trying this our server got hanged.

SO Please help us , how to end the request for particular LUN without ending other request for other LUNs.Because all the scsi requests are going thorugh do_cciss_request only.

Thanks in Advance

NAME

       seeded-in-ubuntu - Determine whether a package is safe to upload during a freeze

SYNOPSIS

       seeded-in-ubuntu [options] package...

DESCRIPTION

       Lists all the current daily images containing the specified packages.  Or whether the package is part of the supported seed.

       If it isn't on an image, it should be safe to upload.  During the final freeze, one should avoid packages in the supported seed too.

       An index of the current manifests is downloaded from UbuntuWire.

OPTIONS

       -b, --binary
	      The  packages  specified	are  binary packages.  This is faster than source packages, as otherwise we must query LP to determine the
	      binary packages that every specified source package builds.

       -u URL, --data-url=URL
	      URL for index of seeded packages.  Default: UbuntuWire's service at http://qa.ubuntuwire.org/ubuntu-seeded-packages/seeded.json.gz.
