[PATCH v11 44/44] sg: bump version to 4.0.11

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that the sg version 4 interface is supported:
  - with ioctl(SG_IO) for synchronous/blocking use
  - with ioctl(SG_IOSUBMIT) and ioctl(SG_IORECEIVE) for
    async/non-blocking use
Plus new ioctl(SG_IOSUBMIT_V3) and ioctl(SG_IORECEIVE_V3)
potentially replace write() and read() for the sg
version 3 interface. Bump major driver version number
from 3 to 4.

The main new feature is the removal of the fixed 16 element
array of requests per file descriptor. It is replaced by
a xarray (eXtensible array) in their parent which is a
sg_fd object (i.e. a file descriptor). The sg_request
objects are not freed until the owning file descriptor is
closed; instead these objects are re-used when multiple
commands are sent to the same file descriptor.
