On workloads that do a lot of multithreaded creates all at once, lock contention on the inodes btree turns out to still be an issue. This patch adds a small buffer of inode numbers that are known to be free, so that we can avoid touching the btree on every create. Also, this changes inode creates to update via the btree key cache for the initial create.

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.
