Subject: userns: Properly print bluetooth socket uids
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With user namespace support enabled building bluetooth generated the warning.
net/bluetooth/af_bluetooth.c: In function ‘bt_seq_show’:
net/bluetooth/af_bluetooth.c:598:7: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 7 has type ‘kuid_t’ [-Wformat]

Convert sock_i_uid from a kuid_t to a uid_t before printing, to avoid
this problem.

Subject: userns: Fix posix_acl_file_xattr_userns gid conversion

The code needs to be from_kgid(make_kgid(...)...) not
from_kuid(make_kgid(...)...). Doh!

When compiling with user namespace support btrfs fails like:

Fix this by using i_uid_read and i_gid_read in
