Linux kernel source tree

The counter update before allocation design was useful to avoid unnecessary scan when device is full, so it will abort early if the counter indicates the device is full. But that is an uncommon case, and now scanning of a full device is very fast, so the up-front update is not helpful any more. Remove it and simplify the slot allocation logic.

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.
