When allocating memory in a loop, each iteration should call memalloc_retry_wait() in order to prevent starving memory-freeing processes (and to mark where allocation loops are). Other filesystems do that as well. The bulk page allocation is the only place in btrfs with an allocation retry loop, so add an appropriate call to it.

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.
