This patchset extends the SCSI generic (sg) driver found in lk 5.3 .
The sg driver has a version number which is visible via an ioctl()
and is bumped from 3.5.36 to 4.0.03 by this patchset.
The additions and changes are described in some detail in this
long webpage:
http://sg.danny.cz/sg/sg_v40.html
Most new features described in the above webpage are not implemented
in this patchset. Features that are not included are file descriptor
sharing, request sharing, multiple requests (in one invocation) and
the extended ioctl(). A latter patchset may add those features. The
SG_IOSUMIT, SG_IOSUBMIT_V3, SG_IORECEIVE and SG_IORECEIVE_V3 ioctls
are added in this patchset.
Testing:
The sg3_utils package has several extensions in sg3_utils-1.45
beta (revision 826) to support and test the version 4 sg
driver presented in this patchset.
The new and revised testing utilities are outlined on the
same webpage as above in the second half of the section
titled: "15 Downloads and testing".
This patchset is against Martin Petersen's 5.3/scsi-queue
branch. It will also apply to lk 5.1 and probably lk 5.0 .
