We have this weird space flushing loop inside inode.c for evict where we'll do the normal LIMIT flush, and then commit the transaction and hope we get our space. This is super janky, and in fact there's really nothing stopping us from using FLUSH_ALL except that we run delayed iputs, which means we could deadlock. So introduce a new flush state for eviction that does the normal priority flushing with all of the states that are safe for eviction. The nice side-effect of this is that we'll try harder for evictions. Previously if (for example generic/269) you had a bunch of other operations happening on the fs you could race with those reservations when committing the transaction, and eventually miss getting a reservation for the evict. With this code we'll have our ticket in place through the transaction commit, so any pinned bytes will go to our pending evictions first.

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.
