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 --- block/Kconfig.iosched | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 block/Kconfig.iosched (limited to 'block/Kconfig.iosched') diff --git a/block/Kconfig.iosched b/block/Kconfig.iosched new file mode 100644 index 000000000..27f11320b --- /dev/null +++ b/block/Kconfig.iosched @@ -0,0 +1,47 @@ +# SPDX-License-Identifier: GPL-2.0 +menu "IO Schedulers" + +config MQ_IOSCHED_DEADLINE + tristate "MQ deadline I/O scheduler" + default y + help + MQ version of the deadline IO scheduler. + +config MQ_IOSCHED_KYBER + tristate "Kyber I/O scheduler" + default y + help + The Kyber I/O scheduler is a low-overhead scheduler suitable for + multiqueue and other fast devices.
