[ Upstream commit1282dea37b] After commit4c7e42552b("erofs: remove useless cache strategy of DELAYEDALLOC"), only one cached I/O allocation strategy is supported: When cached I/O is preferred, page allocation is applied without direct reclaim. If allocation fails, fall back to inplace I/O. Let's get rid of z_erofs_cache_alloctype. No logical changes.

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.
