From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- sound/firewire/packets-buffer.h | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 sound/firewire/packets-buffer.h (limited to 'sound/firewire/packets-buffer.h') diff --git a/sound/firewire/packets-buffer.h b/sound/firewire/packets-buffer.h new file mode 100644 index 000000000..99e963c27 --- /dev/null +++ b/sound/firewire/packets-buffer.h @@ -0,0 +1,27 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef SOUND_FIREWIRE_PACKETS_BUFFER_H_INCLUDED +#define SOUND_FIREWIRE_PACKETS_BUFFER_H_INCLUDED + +#include +#include + +/** + * struct iso_packets_buffer - manages a buffer for many packets + * @iso_buffer: the memory containing the packets + * @packets: an array, with each element pointing to one packet + */ +struct iso_packets_buffer { + struct fw_iso_buffer iso_buffer; + struct { + void *buffer; + unsigned int offset; + } *packets; +}; + +int iso_packets_buffer_init(struct iso_packets_buffer *b, struct fw_unit *unit, + unsigned int count, unsigned int packet_size, + enum dma_data_direction direction); +void iso_packets_buffer_destroy(struct iso_packets_buffer *b, + struct fw_unit *unit); + +#endif -- cgit v1.3.1
