parameters with chmod(1), chown(1) and chgrp(1) on a mounted filesystem.
tmpfs has a mount option to select whether it will wrap at 32- or 64-bit inode
numbers:
======= ========================
inode64 Use 64-bit inode numbers
inode32 Use 32-bit inode numbers
======= ========================
On a 32-bit kernel, inode32 is implicit, and inode64 is refused at mount time.
On a 64-bit kernel, CONFIG_TMPFS_INODE64 sets the default. inode64 avoids the
possibility of multiple files with the same inode number on a single device;
but risks glibc failing with EOVERFLOW once 33-bit inode numbers are reached -
if a long-lived tmpfs is accessed by 32-bit applications so ancient that
opening a file larger than 2GiB fails with EINVAL.
So 'mount -t tmpfs -o size=10G,nr_inodes=10k,mode=700 tmpfs /mytmpfs'
will give you tmpfs instance on /mytmpfs which can allocate 10GB

Architecture Page Table Helpers
===============================
Generic MM expects architectures (with MMU) to provide helpers to create, access
and modify page table entries at various level for different memory functions.
These page table helpers need to conform to a common semantics across platforms.
Following tables describe the expected semantics which can also be tested during
boot via CONFIG_DEBUG_VM_PGTABLE option. All future changes in here or the debug
test need to be in sync.

Look at the writable files. Writing 1 to them will enable the
corresponding debug option. All options can be set on a slab that does
not contain objects. If the slab already contains objects then sanity checks
and tracing may only be enabled. The other options may cause the realignment
of objects.
If the file contains 1, the option is enabled, 0 means disabled. The debug
options from the ``slub_debug`` parameter translate to the following files::
F sanity_checks

Careful with tracing: It may spew out lots of information and never stop if
used on the wrong slab.
