cover Option for scsi_debug to fake removable devices

Hello all,

For the purposes of automatically testing udisks and gvfs automounting I would like to add a parameter to scsi_debug to control the "removable" attribute of the created block device. With that, we can test system-internal and removable drives, as well as CD-ROMs (which scsi_debug can already emulate). udisks requires different privileges for mounting system-internal drives vs. removable/hotpluggable drives.

I wrote a simple kernel patch for this (against linux-next), and tested this quite thoroughly.

I ran the style checker, and it reports two problems:

------------ 8< --------------
WARNING: line over 80 characters
#109: FILE: drivers/scsi/scsi_debug.c:3255:
+ ret |= driver_create_file(&sdebug_driverfs_driver, &driver_attr_removable);

WARNING: Prefer pr_err(... to printk(KERN_ERR, ... #126: FILE: drivers/scsi/scsi_debug.c:3353:
+ printk(KERN_ERR "scsi_debug_init: removable must be 0 or 1\n");
------------ 8< --------------

But as the existing code uses this style in the adjacent lines, I favored consistency over fixing those. If the latter is desired, I'd rather send a separate patch with just the style cleanup for the whole file.

I got a signoff from David Zeuthen (the primary udisks maintainer) already, noted so in the patch.

Thank you in advance for considering,

Martin

PATCH 1/1 scsi_debug: Add "removable" parameter

Add "removable" module parameter to set the "removable" attribute of any subsequently created debug block device. It is a writable driver option, so that you can switch between removable and "fixed" media block devices in between the add_host calls.

This is useful for being able to test the different behaviour/required privileges in e. g. the udisks test suite.

Just like the obsolete printk KERN_ERR and the overly long lines (see my intro mail) I wanted to be consistent with the existing boolean options (the other flags also use an int).

However, I don't mind much either way; if it is preferred, I can send a patch with int → bool.

Thanks,

Martin

I got a signoff from David Zeuthen (the primary udisks maintainer) already, noted so in the patch.

This is wrong. Signed-off would mean that he takes the patch and passed it on. So what this really is as you as the original author push this out is either Acked-by, Tested-by, Reviewed-by or something like that.
