How about something along the lines of

===
struct file_operations ->llseek() method gets called only in two places:
vfs_llseek() and dump_skip().  Both treat NULL and no_llseek as
equivalent.

The value of ->llseek is also examined in __full_proxy_fops_init() and
ovl_copy_up_data().  For the former we could as well treat no_llseek
as NULL; no need to do a proxy wrapper around the function that fails
with -ESPIPE without so much as looking at its arguments.
Same for the latter - there no_llseek would end up with skip_hole
set true until the first time we look at it.  At that point we
call vfs_llseek(), observe that it has failed (-ESPIPE), shrug and
set skip_hole false.  Might as well have done that from the very
beginning.

	In other words, any place where .llseek is set to no_llseek
could just as well set it to NULL.
===

for commit message?

Next commit would remove the checks for no_llseek and have vfs_llseek()
just do
        if (file->f_mode & FMODE_LSEEK) {
		if (file->f_op->llseek)
			return file->f_op->llseek(file, offset, whence);
	}
	return -ESPIPE;
and kill no_llseek() off.  And once you have guaranteed that FMODE_LSEEK
is never set with NULL ->llseek, vfs_llseek() gets trimmed in obvious
way and tests in dump_skip() and ovl_copy_up_data() would become simply
file->f_mode & FMODE_LSEEK - no need to check ->f_op->llseek there
after that.  At the same time dump_skip() could switch to calling
vfs_llseek() instead of direct method call...

Thanks. I'll split things into steps more or less like that and borrow
that commit text for v2 (which I'll send out somewhat soon).
