treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

ide-cd: rename cdrom_read_tocentry

2020-05-04T16:13:42+00:00

Give the cdrom_read_tocentry function and ide_ prefix to not conflict with the soon to be added generic function. Signed-off-by: Christoph Hellwig Reviewed-by: Damien Le Moal Reviewed-by: Hannes Reinecke Signed-off-by: Jens Axboe

block: add a cdrom_device_info pointer to struct gendisk

2020-05-04T16:13:42+00:00

Add a pointer to the CDROM information structure to struct gendisk. This will allow various removable media file systems to call directly into the CDROM layer instead of abusing ioctls with kernel pointers. Signed-off-by: Christoph Hellwig Reviewed-by: Damien Le Moal Signed-off-by: Jens Axboe

compat_ioctl: move HDIO ioctl handling into drivers/ide

2020-01-03T08:42:52+00:00

Most of the HDIO ioctls are only used by the obsolete drivers/ide subsystem, these can be handled by changing ide_cmd_ioctl() to be aware of compat mode and doing the correct transformations in place and using it as both native and compat handlers for all drivers. The SCSI drivers implementing the same commands are already doing this in the drivers, so the compat_blkdev_driver_ioctl() function is no longer needed now. The BLKSECTSET and HDIO_GETGEO_BIG ioctls are not implemented in any driver any more and no longer need any conversion. Reviewed-by: Ben Hutchings Signed-off-by: Arnd Bergmann

compat_ioctl: move cdrom commands into cdrom.c

2020-01-03T08:42:52+00:00

There is no need for the special cases for the cdrom ioctls any more now, so make sure that each cdrom driver has a .compat_ioctl() callback and calls cdrom_compat_ioctl() directly there. Reviewed-by: Ben Hutchings Signed-off-by: Arnd Bergmann

docs: cdrom: convert docs to ReST and rename to *.rst

2019-06-14T20:20:46+00:00

The stuff there is almost already at ReST format. A conversion for them is trivial: just add a missing titles and fix some scape codes for them to match ReST syntax. While here, rename the cdrom-standard.txt, with was converted from LaTeX to ReST on the previous patch, and add it to the index file. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jonathan Corbet

Revert "ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd"

2019-04-12T19:35:25+00:00

This reverts commit 7eec77a1816a7042591a6cbdb4820e9e7ebffe0e. Instead of leaving disk->events completely empty, we now export the supported events again, and tell the block layer not to forward events to user space by not setting DISK_EVENT_FLAG_UEVENT. This allows the block layer to distinguish between devices that for which events should be handled in kernel only, and devices which don't support any meda change events at all.

ide: don't use req->special

Just replace it with a field of the same name in struct ide_req. Reviewed-by: Hannes Reinecke Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

ide: cleanup ->prep_rq calling convention

2018-11-10T02:17:13+00:00

The return value is just used as a binary yes/no decision, so switch it to a bool instead of the old BLKPREP_* values returned as an int. Also clean up a few related comments. Reviewed-by: Bart Van Assche Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

ide: convert to blk-mq

2018-11-07T20:42:31+00:00

ide-disk and ide-cd tested as working just fine, ide-tape and ide-floppy haven't. But the latter don't require changes, so they should work without issue. Add helper function to insert a request from a work queue, since we cannot invoke the blk-mq request insertion from IRQ context.
