Instead of handling the card-specific resource in snd_device, attach it into pcm->private_data and release it directly in private_free. This simplifies the code and structure. Tested-by:

Instead of sysfs and the conditional build with Kconfig, implement the handling of the impulse response controls via control API, and always enable the build. Two new controls, "Impulse Response Volume" and "Impulse Response Period" are added as a replacement for the former sysfs files. Tested-by:

Split to each individual driver for POD, PODHD, TonePort and Variax with a core LINE6 helper module. The new modules follow the standard ALSA naming rule with snd prefix: snd-usb-pod, snd-usb-podhd, snd-usb-toneport and snd-usb-variax, together with the corresponding CONFIG_SND_USB_* Kconfig items.

Which *_disconnect() to call on disconnect is known at initialization. Add a function pointer to the `usb_line6' struct and use to call into the appropriate logic instead of evaluating the conditional logic. Signed-off-by:

The `LINE6_CAP_CTRL_PCM_HW' macro combines three capabilities to save horizontal space when defining the properties entries. Now that these are no longer limited to single lines this is not such a concern. Specify capabilities individually when defining each property for better clarity. Signed-off-by:

Specify the index of the properties entry explicitly to define this structure more robustly. Also, drop the `L6PROP' macro in favor of initializing each member explicitly on its own line since horizontal space is limited and more attributes will be added later. Signed-off-by:

These are now only used to build the device table. Each entry in this table is already clearly documented as to what device it maps to so the macros become unnecessary indirection. Signed-off-by:

The driver currently uses the device's idProduct as input to several switch statements. In some cases this is not sufficiently granular and the interface number must be taken into account. Store the device type in `usb_line6' and key off of it instead. New types can then be added that map to specific interfaces on the device so that this conditional logic can be flattened out.

The current logic uses the index of the matched entry from the device table as an offset to the corresponding properties entry. The values of the new `line6_device_type' enum are ordered such that they can be used as an index into either of these arrays. Drop the device entry lookup logic and use the device type (via the .driver_info member) instead. Signed-off-by:

Fix for BUG_ON(anon_vma->degree) splashes in unlink_anon_vmas() ("kernel BUG at mm/rmap.c:399!") caused by commit 7a3ef208 ("mm: prevent endless growth of anon_vma hierarchy") Anon_vma_clone() is usually called for a copy of source vma in destination argument. If source vma has anon_vma it should be already in dst->anon_vma. NULL in dst->anon_vma is used as a sign that it's called from anon_vma_fork(). In this case anon_vma_clone() finds anon_vma for reusing. Vma_adjust() calls it differently and this breaks anon_vma reusing logic: anon_vma_clone() links vma to old anon_vma and updates degree counters but vma_adjust() overrides vma->anon_vma right after that. As a result final unlink_anon_vmas() decrements degree for wrong anon_vma. This patch assigns ->anon_vma before calling anon_vma_clone().

Commit fee7e49d ("mm: propagate error from stack expansion even for guard page") made sure that we return the error properly for stack growth conditions. It also theorized that counting the guard page towards the stack limit might break something, but also said "Let's see if anybody notices". Somebody did notice. Apparently android-x86 sets the stack limit very close to the limit indeed, and including the guard page in the rlimit check causes the android 'zygote' process problems. So this adds the (fairly trivial) code to make the stack rlimit check be against the actual real stack size, rather than the size of the vma that includes the guard page. Reported-and-tested-by:
