Hi all!

While analyzing debug logs of our customer, I've noticed strange looking
lines like:

[2018/05/09 16:02:52.629315, 10, pid=907, effective(1001, 1001), real(0,
0)] ../source3/smbd/open.c:5543(create_file_default)
  create_file: access_mask = 0x100080 file_attributes = 0x10, share_access
= 0x7, create_disposition = 0x1 create_options = 0x1 oplock_request = 0x0
private_flags = 0x0 root_dir_fid = 0x0, ea_list = 0x0x0, sd = 0x0x0, fname
= .

That 0x0x0 puzzled me and short investigation showed that in few places we
use "0x%p" format string to represent buffer address in the debug logs. Man
page for *printf says:

     p           The void * pointer argument is printed in hexadecimal (as
                 by ‘%#x’ or ‘%#lx’).

I.e. the address will be already prefixed with the 0x, no need to
explicitly add it.

Here is a small patch.

With regards,
Timur Bakeyev.
