Subject: [GIT PULL] vfs netfs
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.
