When direct writes fail with -ENOTBLK because we're writing into a hole (gfs2_iomap_begin()) or because of a page invalidation failure (iomap_dio_rw()), we're falling back to buffered writes. In that case, when we lose the inode glock in gfs2_file_buffered_write(), we want to re-acquire it instead of returning a short write. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
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.
