- addition of ftrace hooks for cifs.ko
- improvements in compounding and smbdirect (rdma)
* tag '4.18-smb3-fixes' of git://git.samba.org/sfrench/cifs-2.6: (38 commits)
CIFS: Add support for direct pages in wdata
CIFS: Use offset when reading pages
CIFS: Add support for direct pages in rdata
cifs: update multiplex loop to handle compounded responses
cifs: remove header_preamble_size where it is always 0
cifs: remove struct smb2_hdr
CIFS: 511c54a2f69195b28afb9dd119f03787b1625bb4 adds a check for session expiry, status STATUS_NETWORK_SESSION_EXPIRED, however the server can also respond with STATUS_USER_SESSION_DELETED in cases where the session has been idle for some time and the server reaps the session to recover resources.
cifs: change smb2_get_data_area_len to take a smb2_sync_hdr as argument
cifs: update smb2_calc_size to use smb2_sync_hdr instead of smb2_hdr
cifs: remove struct smb2_oplock_break_rsp
cifs: remove rfc1002 header from all SMB2 response structures
smb3: on reconnect set PreviousSessionId field
smb3: Add posix create context for smb3.11 posix mounts
smb3: add tracepoints for smb2/smb3 open
cifs: add debug output to show nocase mount option
smb3: add define for id for posix create context and corresponding struct
cifs: update smb2_check_message to handle PDUs without a 4 byte length header
smb3: allow "posix" mount option to enable new SMB311 protocol extensions
smb3: add support for posix negotiate context
cifs: allow disabling less secure legacy dialects
