This adds a new helper, bch2_folio_reservation_get_partial(), which reserves as many blocks as possible and may return partial success. __bch2_buffered_write() is switched to the new helper - this fixes fstests generic/275, the write until -ENOSPC test. generic/230 now fails: this appears to be a test bug, where xfs_io isn't looping after a partial write to get the error code.

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.
