zram_write_page() handles: ZRAM_SAME pages (which was already factored out) stores, regular page stores and ZRAM_HUGE pages stores. ZRAM_HUGE handling adds a significant amount of complexity. Instead, we can handle ZRAM_HUGE in a separate function. This allows us to simplify zs_handle allocations slow-path, as it now does not handle ZRAM_HUGE case. ZRAM_HUGE zs_handle allocation, on the other hand, can now drop __GFP_KSWAPD_RECLAIM because we handle ZRAM_HUGE in preemptible context (outside of local-lock scope).

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.
