virt: vbox: utils: fix all kernel-doc warnings

2023-12-23T13:15:46+00:00

Use kernel-doc format for functions that have comments that begin with "/**". This prevents 6 kernel-doc warnings.

virt: vbox: linux: fix all kernel-doc warnings

2023-12-23T13:15:45+00:00

Use kernel-doc format for functions that are almost complete in their kernel-doc comments. For other functions, just change the comment to a common C comment. This prevents 7 kernel-doc warnings.

virt: vbox: Remove unproper information

2022-09-09T08:19:18+00:00

When drivers are working properly, they are quiet. Therefore, the vbg_info() should be removed. Suggested-by: Greg Kroah-Hartman Reviewed-by: Hans de Goede Signed-off-by: Jiasheng Jiang Link: https://lore.kernel.org/r/20220901144619.3550352-1-jiasheng@iscas.ac.cn Signed-off-by: Greg Kroah-Hartman

virt: vbox: convert to use dev_groups

2022-09-09T08:19:04+00:00

The driver core supports the ability to handle the creation and removal of device-specific sysfs files in a race-free manner. Moreover, it can guarantee the success of creation. Therefore, it should be better to convert to use dev_groups.

virt: move from strlcpy with unused retval to strscpy

2022-09-01T14:29:46+00:00

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

vboxguest: Do not use devm for irq

When relying on devm it doesn't get freed early enough which causes the following warning when unloading the module: [249348.837181] remove_proc_entry: removing non-empty directory 'irq/20', leaking at least 'vboxguest' [249348.837219] WARNING: CPU: 0 PID: 6708 at fs/proc/generic.c:715 remove_proc_entry+0x119/0x140 [249348.837379] Call Trace: [249348.837385] unregister_irq_proc+0xbd/0xe0 [249348.837392] free_desc+0x23/0x60 [249348.837396] irq_free_descs+0x4a/0x70 [249348.837401] irq_domain_free_irqs+0x160/0x1a0 [249348.837452] mp_unmap_irq+0x5c/0x60 [249348.837458] acpi_unregister_gsi_ioapic+0x29/0x40 [249348.837463] acpi_unregister_gsi+0x17/0x30 [249348.837467] acpi_pci_irq_disable+0xbf/0xe0 [249348.837473] pcibios_disable_device+0x20/0x30 [249348.837478] pci_disable_device+0xef/0x120 [249348.837482] vbg_pci_remove+0x6c/0x70 [vboxguest] Reviewed-by: Hans de Goede Signed-off-by: Pascal Terjan Link: https://lore.kernel.org/r/20220612133744.4030602-1-pterjan@google.com Signed-off-by: Greg Kroah-Hartman

virt: vbox: Do not use wait_event_interruptible when called from kernel context

2021-01-27T13:37:02+00:00

Do not use wait_event_interruptible when vbg_hgcm_call() gets called from kernel-context, such as it being called by the vboxsf filesystem code. This fixes some filesystem related system calls on shared folders unexpectedly failing with -EINTR.
