With the recent rework of the inode cluster flushing, we no longer ever wait on the the inode flush "lock". It was never a lock in the first place, just a completion to allow callers to wait for inode IO to complete. We now never wait for flush completion as all inode flushing is non-blocking. Hence we can get rid of all the iflock infrastructure and instead just set and check a state flag. Rename the XFS_IFLOCK flag to XFS_IFLUSHING, convert all the xfs_iflock_nowait() test-and-set operations on that flag, and replace all the xfs_ifunlock() calls to clear operations.

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.
