[PATCH] sanitize locate_fd()
* 'file' argument is unused; lose it.
* move setting flags from the caller (dupfd()) to locate_fd();
pass cloexec flag as new argument. Note that files_fdtable()
that used to be in dupfd() isn't needed in the place in
locate_fd() where the moved code ends up - we know that ->file_lock
hadn't been dropped since the last time we calculated fdt because
we can get there only if expand_files() returns 0 and it doesn't
drop/reacquire in that case.
* move getting/dropping ->file_lock into locate_fd(). Now the caller
doesn't need to do anything with files_struct *files anymore and
we can move that inside locate_fd() as well, killing the
struct files_struct * argument.
At that point locate_fd() is extremely similar to get_unused_fd_flags()
and the next patches will merge those two.
