ext2_xattr_cache_insert() calls mb_cache_entry_create() with GFP_NOFS because it is called under EXT2_I(inode)->xattr_sem. However xattr_sem or any higher ranking lock is not acquired on fs reclaim path for ext2 at least since we don't do page writeback from direct reclaim. Thus GFP_NOFS is not needed.

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.
