paride/pcd: use bdev_check_media_change

2020-09-10T15:32:31Z

The pcd driver does not have a ->revalidate_disk method, so it can just use bdev_check_media_change without any additional changes. Signed-off-by: Christoph Hellwig Reviewed-by: Johannes Thumshirn Reviewed-by: Hannes Reinecke Signed-off-by: Jens Axboe

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

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.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

block: add a cdrom_device_info pointer to struct gendisk

2020-05-04T16:13:42Z

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

scsi: compat_ioctl: cdrom: Replace .ioctl with .compat_ioctl in four appropriate places

2020-02-24T20:06:07Z

Arnd Bergmann inadvertently typoed these in d320a9551e394 and 64cbfa96551a; they seem to be the cause of https://bugzilla.redhat.com/show_bug.cgi?id=1801353 , invalid SCSI commands when udev tries to query a DVD drive. [arnd] Found another instance of the same bug, also introduced in my compat_ioctl series.

compat_ioctl: move cdrom commands into cdrom.c

2020-01-03T08:42:52Z

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

compat_ioctl: block: handle cdrom compat ioctl in non-cdrom drivers

2020-01-03T08:33:15Z

Various block drivers implement the CDROMMULTISESSION, CDROM_GET_CAPABILITY, and CDROMEJECT ioctl commands, relying on the block layer to handle compat_ioctl mode for them. Move this into the drivers directly as a preparation for simplifying the block layer later. When only integer arguments or no arguments are passed, the same handler can be used for .ioctl and .compat_ioctl, and when only pointer arguments are passed, the newly added blkdev_compat_ptr_ioctl can be used.
