When an allocation happens from process context rather than filesystem context, it is best to use GFP_KERNEL rather than LIBCFS_ALLOC() which always uses GFP_NOFS. This include initialization during, or prior to, mount, and code run from separate worker threads. So for some of these cases, switch to kmalloc, kvmalloc, or kvmalloc_array() as appropriate. In some cases we preserve __GFP_ZERO (via kzalloc/kvzalloc), but in others it is clear that allocated memory is immediately initialized. In each case, the matching LIBCFS_FREE() is converted to kfree() or kvfree() This is just a subset of locations that need changing. As there are quite a lot, I've broken them up into several ad-hoc sets to avoid review-fatigue.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
