Add a limited write failure mode which allows a write to a block to fail a specified amount of times, prior to remapping. The "addbadblock" message is extended to allow specifying the limited number of times a write fails. Example: add bad block on block 60, with 5 write failures: dmsetup message 0 dust1 addbadblock 60 5 The write failure counter will be printed for newly added bad blocks.

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 Restructured Text 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.
