In preparation for assigning some inode space to extended attributes, keep track of free_ispace instead of number of free_inodes: as if one tmpfs inode (and accompanying dentry) occupies very approximately 1KiB. Unsigned long is large enough for free_ispace, on 64-bit and on 32-bit: but take care to enforce the maximum. And fix the nr_blocks maximum on 32-bit: S64_MAX would be too big for it there, so say LONG_MAX instead. Delete the incorrect limited<->unlimited blocks/inodes comment above shmem_reconfigure(): leave it to the error messages below to describe.

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.
