    Pull smb client fixes from Paulo Alcantara:
     "Fix a series of data corruption and I/O error bugs found by running
      generic/363 (fsx) in a loop against Windows Server 2022 and Samba.

       - Stop data dirtied past EOF through an mmap from reappearing as file
         content once the file is extended by a write, truncate, zero range,
         copy range or clone range

       - Flush dirty data and drain in-flight I/O before operations that
         assume the pagecache and the server agree on the file: querying
         allocated ranges, the O_TRUNC open, interior zero range, and
         server-side copy/clone

       - Stop a genuine size-extending zero range or preallocate from being
         refused with -EOPNOTSUPP when the inode is not read caching, by
         querying the server's authoritative EOF instead of trusting a stale
         cached i_size

       - Zero the untransferred tail of a short read, both in the netfs
         read-gaps path (where stale folio content could otherwise be
         written back to the server) and in the DIO/unbuffered read
         collector, and tell a real EOF apart from a stale cached
         remote_i_size after a lease downgrade

       - Require stable pages on signed connections so a buffered write
         can't modify a folio whose signature has already been computed and
         is in flight, which the server rejected with STATUS_ACCESS_DENIED
         and the client surfaced as -EIO

       - Split several cifsFileInfo flags out of a shared bitfield byte so
         concurrent updates taken under different locks no longer clobber
         each other through a byte-level RMW"
