I updated patch 2
(0002-fs-smb-client-Implement-new-SMB3-POSIX-type.patch) to address
various checkpatch warnings, and added one small changeset to fix
mounts to older servers which don't fill in the file type in the level
100 Mode field (0004-smb3.1.1-fix-posix-mounts-to-older-servers.patch),
and updated them in cifs-2.6.git for-next. Let me know if any
objections. It looks like it does make a big improvement in reporting
special files when mounted to Samba, but want to figure out why the
dentry cache (revalidate call) still requires the extra roundtrip per
file when doing "ls -l" (there may be a way that this enhanced query
dir output could be recognized as still valid, and reduce need for
extra queries).
See attached.

Subject: [PATCH 4/4] smb3.1.1: fix posix mounts to older servers
Some servers which implement the SMB3.1.1 POSIX extensions did not
set the file type in the mode in the infolevel 100 response.
With recent changes for checking the file type via the mode field,
this can cause the root directory to be reported incorrectly and
mounts (e.g. to ksmbd) to fail.
