do_sendfile() prefers splice over sendfile, so it should not trigger (directly, at least). Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Remove shmem_file_sendfile and resurrect shmem_readpage, as used by tmpfs to support loop and sendfile in 2.4 and 2.5. Now tmpfs can support splice, loop and sendfile in the simplest way, using generic_file_splice_read and generic_file_splice_write (with the aid of shmem_prepare_write). We could make some efficiency tweaks later, if there's a real need; but this is stable and works well as is.

It cleans up the relay splice implementation a lot, and gets rid of a lot of internal pipe knowledge that should not be in there. Plus fixes for padding and partial first page (and lots more) from Tom Zanussi. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

relay needs this for proper consumption handling, and the network receive support needs it as well to lookup the sk_buff on pipe release. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

We need to move even more stuff into the header so that folks can use the splice_to_pipe() implementation instead of open-coding a lot of pipe knowledge (see relay implementation), so move to our own header file finally. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

This gets rid of the dependency on ->sendfile() for receiving data and converts loop to ->splice_read() instead. Also includes an IV offset fix from Hugh Dickins. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

They can use generic_file_splice_read() instead. Since sys_sendfile() now prefers that, there should be no change in behaviour. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

This patch makes sendfile prefer to use ->splice_read(), if it's available in the file_operations structure. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

A bit of a cheat, it actually just copies the data to userspace. But this makes the interface nice and symmetric and enables people to build on splice, with room for future improvement in performance. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>
-
由 Jens Axboe 提交于
For direct splicing (or private splicing), the output may not be a file. So abstract out the handling into a specified actor function and put the data in the splice_desc structure earlier, so we can build on top of that. This is the first step in better splice handling for drivers, and also for implementing vmsplice _to_ user memory. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Add rudimentary check for the case that the page table overflows due to merging of s/g elements by the IOMMU. This would have lead to overwriting of arbitrary memory. After this change I expect that an offending command will be unsuccessfully retried until the scsi_device is taken offline by SCSI core. It's a border case and not worth to implement a recovery strategy. Signed-off-by: NStefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: NKristian Høgsberg <krh@redhat.com>

Use a speed probe to determine the speed over 1394b buses and of nodes which report a link speed less than their PHY speed. Log the effective maximum speed of newly created nodes in dmesg. Also, read the config ROM (except bus info block) at the maximum speed rather than S100. This isn't a real optimization though because we still only use quadlet read requests for the entire ROM. The patch also adds support for S1600 and S3200, although such hardware does not exist yet.

Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. This patch also removes the underlying facilities in ohci1394 and disables them in pcilynx. That is, hpsb_host_driver.devctl() and hpsb_host_driver.transmit_packet() are no longer used for iso reception and transmission. Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts.

This is upwards compatible, except that integer values other than 0 or 1 are no longer accepted. But values like "Y", "N", "no", "nnoooh!" work now.

After ieee1394 was converted away from class_device like the networking subsystem was already in 2.6.21, eth1394's device may point to the fw-host device as its parent again like in 2.6.20. This affects userspace tools which examine the sysfs representation of eth1394's device. Signed-off-by: NStefan Richter <stefanr@s5r6.in-berlin.de>
