Merge tag 'vfs-6.10.netfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull netfs updates from Christian Brauner:
"This reworks the netfslib writeback implementation so that pages read
from the cache are written to the cache through ->writepages(),
thereby allowing the fscache page flag to be retired.

The reworking also:

- builds on top of the new writeback_iter() infrastructure

- makes it possible to use vectored write RPCs as discontiguous
streams of pages can be accommodated

- makes it easier to do simultaneous content crypto and stream
division

- provides support for retrying writes and re-dividing a stream

- replaces the ->launder_folio() op, so that ->writepages() is used
instead

- uses mempools to allocate the netfs_io_request and
netfs_io_subrequest structs to avoid allocation failure in the
writeback path

Some code that uses the fscache page flag is retained for
compatibility purposes with nfs and ceph. The code is switched to
using the synonymous private_2 label instead and marked with
deprecation comments.

The merge commit contains additional details on the new algorithm that
I've left out of here as it would probably be excessively detailed.

On top of the netfslib infrastructure this contains the work to
convert cifs over to netfslib"

cifs: Implement netfslib hooks

Provide implementation of the netfslib hooks that will be used by netfslib
to ask cifs to set up and perform operations. Of particular note are

(*) cifs_clamp_length() - This is used to negotiate the size of the next
subrequest in a read request, taking into account the credit available
and the rsize. The credits are attached to the subrequest.

(*) cifs_req_issue_read() - This is used to issue a subrequest that has
been set up and clamped.

(*) cifs_prepare_write() - This prepares to fill a subrequest by picking a
channel, reopening the file and requesting credits so that we can set
the maximum size of the subrequest and also sets the maximum number of
segments if we're doing RDMA.

(*) cifs_issue_write() - This releases any unneeded credits and issues an
asynchronous data write for the contiguous slice of file covered by
the subrequest. This should possibly be folded in to all
->async_writev() ops and that called directly.

(*) cifs_begin_writeback() - This gets the cached writable handle through
which we do writeback (this does not affect writethrough, unbuffered
or direct writes).

At this point, cifs is not wired up to actually *use* netfslib; that will
be done in a subsequent patch.
