Once the unmatched stride IO mode is detected, shrink the stride-ahead window to 0.
if it does hit cache miss, and read-pattern is still stride-io mode,

1) set root permission mode as 0755 before test.
2) scripts cleanup.

Return a protocol error from ost_punch() like all other handler methods
if there is a request format error, instead of -EINVAL.

Rename "pages" pointer to "npages", because it otherwise looks like an
array of pointers to pages instead of a pass-by-reference number of pages.

Move HAVE_PAGE_CONSTANT checks out-of-line via compat macros.

Remove unnecessary cast of void pointers.

copy_{to,from}_user() do not return an error code, but rather the number
of uncopied bytes (0 if all bytes were copied).  Storing this return value
into "rc" is misleading because it then seems this should be returned to
the caller of the function.

Code was audited to remote storing of the return value into "rc" and
several incorrect uses were found.
