Subject: [PATCH v6 37/37] sg: bump version to 4.0.08
Date: Mon, 13 Jan 2020 00:57:55 +0100	[thread overview]
Message-ID: <20200112235755.14197-38-dgilbert@interlog.com> (raw)
In-Reply-To: <20200112235755.14197-1-dgilbert@interlog.com>

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.
