In the OCSSD 2.0 spec, each chunk reports its write pointer. This means that pblk does not need to scan open lines to find the write pointer, but instead, it can retrieve it directly (and verify it). This patch uses the write pointer on open lines to (i) recover the line up until the last written lba and (ii) reconstruct the map bitmap and rest of line metadata so that the line can be used for new data. Since the 1.2 path in lightnvm core has been re-implemented to populate the chunk structure and thus recover the write pointer on initialization, this patch removes 1.2 specific recovery, as the 2.0 path can be reused.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
