In the past, the function __vmalloc didn't respect the GFP flags - it allocated memory with the provided gfp flags, but it allocated page tables with GFP_KERNEL. This was fixed in commit451769ebb7("mm/vmalloc: alloc GFP_NO{FS,IO} for vmalloc") so the memalloc_noio_{save,restore} workaround is no longer needed. The function kvmalloc didn't like flags different from GFP_KERNEL. This was fixed in commita421ef3030("mm: allow !GFP_KERNEL allocations for kvmalloc"), so kvmalloc can now be called with GFP_NOIO.

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.
