We're unnecessarily limiting the size of an ACL to less than what most filesystems will support. Some users do hit the limit and it's confusing and unnecessary. It still seems prudent to impose some limit on the number of ACEs the client gives us before passing it straight to kmalloc(). So, let's just limit it to the maximum number that would be possible given the amount of data left in the argument buffer. That will still leave one limit beyond whatever the filesystem imposes: the client and server negotiate a limit on the size of a request, which we have to respect. But we're no longer imposing any additional arbitrary limit. struct nfs4_ace is 20 bytes on my system and the maximum call size we'll negotiate is about a megabyte, so in practice this is limiting the allocation here to about a megabyte.

README
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.
