[GIT PULL] vfs netfs

[Christian Brauner]

Hey Linus,

A quick word on the general timing for netfs pull requests going
forward. In contrast to most of the other work I tend to send the netfs
updates a little later and will probably continue to do so in the
future. In the past we had some issues with late-stage fixes or there
were complicated merge conflicts with other trees or mainline that were
a little unusal. So since there's more jitter in how consistently this
tree can be carried through a cycle I'm letting this reflect in the pull
request timing as well.

/* Summary */

This contains the netfs updates for this cycle:

- The main API document has been extensively updated/rewritten.

- Fix an oops in write-retry due to mis-resetting the I/O iterator.

- Fix the recording of transferred bytes for short DIO reads.

- Fix a request's work item to not require a reference, thereby avoiding
  the need to get rid of it in BH/IRQ context.

- Fix waiting and waking to be consistent about the waitqueue used.

- Remove NETFS_SREQ_SEEK_DATA_READ.

- Remove NETFS_INVALID_WRITE.

- Remove NETFS_ICTX_WRITETHROUGH.

- Remove NETFS_READ_HOLE_CLEAR.

- Reorder structs to eliminate holes.

- Remove netfs_io_request::ractl.

- Only provide proc_link field if CONFIG_PROC_FS=y.

- Remove folio_queue::marks3.

- Remove NETFS_RREQ_DONT_UNLOCK_FOLIOS.

- Remove NETFS_RREQ_BLOCKED.

- Fix undifferentiation of DIO reads from unbuffered reads.
