The name of the pvrusb2 module is not likely to ever change, and there

is little utility in using a macro to infer the module name here. In
addition, using that macro complicates other uses of the driver
involving older kernels where this macro works differently. Yes I
know for many places we don't have to worry about that. But my
alternative is that I have to build special logic in the pvrusb2
standalone driver to special-case what is otherwise costmetic and that
is just plain nuts for something as trivial as this, especially since
this change does not at all have any compile time or run time impact
on the driver. I'm just removing a nicety that didn't have a lot of

fix setuid sometimes doesn't
Joe Malicki reports that setuid sometimes doesn't: very rarely,
a setuid root program does not get root euid; and, by the way,
they have a health check running lsof every few minutes.
Right, check_unsafe_exec() notes whether the files_struct is being
shared by more threads than will get killed by the exec, and if so
sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid.
But /proc/<pid>/fd and /proc/<pid>/fdinfo lookups make transient
use of get_files_struct(), which also raises that sharing count.
There's a rather simple fix for this: exec's check on files->count
has been redundant ever since 2.6.1 made it unshare_files() (except
while compat_do_execve() omitted to do so) - just remove that check.
[Note to -stable: this patch will not apply before 2.6.29: earlier
releases should just remove the files->count line from unsafe_exec().]
