Pull smb client fixes from Paulo Alcantara:

 - Fixes for fallocate range operations (insert, collapse, zero, punch
   hole)

   The insert range implementation copied overlapping chunks in the
   wrong direction, corrupting file data on every server except Windows.

   Several related issues in the same area are also addressed — stale
   page cache and FS-Cache readback, an integer truncation on large
   files, missing RLIMIT_FSIZE validation and missing sparse file
   marking.

 - Data corruption fixes in the O_TRUNC open path: one where i_size was
   zeroed before the server confirmed the truncate and another where the
   lack of locking allowed concurrent buffered writes to be silently
   discarded

 - Heap overflow fixes in legacy SMB1 paths: one in extended attribute
   writes and one in POSIX ACL handling, both exploitable via
   unprivileged setxattr(2)

 - Fix for multiuser mount with krb5 failing because the username option
   was not propagated to new per-user connections

 - Fix for split debug message in __release_mid() after a printk
   conversion
