The tape is implemented as fixed number (10 000) of 8-byte units. The first four bytes of a unit contains the type of the unit (data block, filemark or end-of-data mark). If the units is a data block, the first four bytes contain the block length and the remaining four bytes the first bytes of written data. This allows the user to use tags to see that the read block is what it was supposed to be. The tape can contain two partitions. Initially it is formatted as one partition consisting of all 10 000 units. This patch adds the WRITE(6) command for tapes and the WRITE FILEMARKS (6) command. The REWIND command is updated.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
