  smb: client: only use a single wait_queue to monitor smbdirect
connection status (2025-08-07 12:40:11 -0500)

----------------------------------------------------------------
33 smb3/cifs client changesets, mostly smbdirect cleanup

Eight non-smbdirect fixes
 - Fix null ptr deref caused by delay in global spinlock initialization
 - Two fixes for native symlink creation with SMB3.1.1 POSIX Extensions
 - Fix for socket special file creation with SMB3.1.1 POSIX Exensions
 - Reduce lock contention by splitting out mid_counter_lock
    - move SMB1 transport code to separate file to reduce module size
      when support for legacy servers is disabled
 - Two cleanup patches: rename mid_lock to make it clearer what it protects
   and one to convert mid flags to bool to make clearer

Twenty five smbdirect/RDMA restructuring patches and fixes
 - Fix for error handling in send done
 - Remove unneeded empty packet queue
 - Fix put_receive_buffer error path
 - Two fixes to recv_done error paths
 - Remove unused variable
 - Improve response and recvmsg type handling
 - Fix handling of incoming message type
 - Two cleanup fixes for better handling smbdirect recv io
 - Two cleanup fixes for socket spinlock
 - Two patches that add socket reassembly struct
 - Remove unused connection_status enum
 - Use flag in common header for SMBDIRECT_RECV_IO_MAX_SGE
 - Two cleanup patches to introduce and use smbdirect send io
 - Two cleanup patches to introduce and use smbdirect send_io struct
 - Fix to return error if rdma connect takes longer than 5 seconds
 - Error logging improvements
 - Fix redundand call to init_waitqueue_head
 - Remove unneeded wait queue
