Seems copied from sysfs, but I don't see a reason here nor there to use
a semaphore instead of a mutex. Convert.

The attribute store/show code currently limits attributes at PAGE_SIZE.
This code comes from sysfs, where it still works that way.
However, PAGE_SIZE is not constant. A 16k attribute string works on
ia64 but not on x86. Really a subsystem shouldn't allow different
attribute sizes based on platform.
As such, limit all simple attributes to 4k. This works on all
platforms, and is consistent with all current code.

Attributes in configfs are text files. As such, most handlers expect to be
able to call functions like simple_strtoul() without checking the bounds
of the buffer. Change the call to zero terminate the buffer before calling
the client's ->store() method. This does reduce the attribute size from
PAGE_SIZE to PAGE_SIZE-1.
Also, change get_zeroed_page() to alloc_page(), as we are handling the
termination.

This is a conversion to make the various file_operations structs in fs/
const. Basically a regexp job, with a few manual fixups
The goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)

configfs always made item and attribute ownership root.root and
permissions based on a umask of 022. Add ->setattr() to allow
chown(2)/chmod(2), and persist the changes for the lifetime of the

This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.
