If the call to btrfs_set_extent_delalloc() fails we are always returning VM_FAULT_SIGBUS, which is odd since the error means "bad access" and the most likely cause for btrfs_set_extent_delalloc() is -ENOMEM, which should be translated to VM_FAULT_OOM. Instead of returning VM_FAULT_SIGBUS return vmf_error(ret2), which gives us a more appropriate return value, and we use that everywhere else too.

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.
