#     Merge tag '6.3-rc-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
#     
#     Pull cifs client updates from Steve French:
#      "The largest subset of this is from David Howells et al: making the
#       cifs/smb3 driver pass iov_iters down to the lowest layers, directly to
#       the network transport rather than passing lists of pages around,
#       helping multiple areas:
#     
#        - Pin user pages, thereby fixing the race between concurrent DIO read
#          and fork, where the pages containing the DIO read buffer may end up
#          belonging to the child process and not the parent - with the result
#          that the parent might not see the retrieved data.
#     
#        - cifs shouldn't take refs on pages extracted from non-user-backed
#          iterators (eg. KVEC). With these changes, cifs will apply the
#          appropriate cleanup.
#     
#        - Making it easier to transition to using folios in cifs rather than
#          pages by dealing with them through BVEC and XARRAY iterators.
#     
#        - Allowing cifs to use the new splice function
#     
#       The remainder are:
#     
#        - fixes for stable, including various fixes for uninitialized memory,
#          wrong length field causing mount issue to very old servers,
#          important directory lease fixes and reconnect fixes
#     
#        - cleanups (unused code removal, change one element array usage, and
#          a change form strtobool to kstrtobool, and Kconfig cleanups)
#     
#        - SMBDIRECT (RDMA) fixes including iov_iter integration and UAF fixes
#     
#        - reconnect fixes
#     
#        - multichannel fixes, including improving channel allocation (to
#          least used channel)
#     
#        - remove the last use of lock_page_killable by moving to
#          folio_lock_killable"
