Merge tag 'timers-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource - Use designated initializers for sh_mtu2, sh_cmt, and sh_tmu, and drop the unused initializer in the platform_device_id table for sh_mtu2 (Uwe Kleine-König) - Remove redundant dev_err()/dev_err_probe() messages when devm_request_*_irq() fails, as the helper already logs an error message (Pan Chuang) - Fix a boot hang on Allwinner D1 when a forced minimum delta is used with the sun4i timer (Felix Yan) - Fix an IRQ leak in the cpuhp_setup_state() error path by freeing the IRQ on failure in the NXP PIT driver (WenTao Liang) - Fix incorrect unmapping of shared MMIO between the clocksource and clockevent drivers. If one of them fails to initialize, the error path unmaps the shared MMIO region, leaving the other driver with an invalid mapping on clps711x (Guangshuo Li) - Make the samsung_pwm driver compatible with PREEMPT_RT by replacing regular spinlocks with raw_spinlock_t in atomic contexts (Marek Szyprowski) - Use __raw_readl() and __raw_writel() instead of ioread32() and iowrite32() to support SWAP_IO_SPACE in the rtl-otto driver (Rustam Adilov) - Fix a missing clk_disable_unprepare() call in the timer initialization error path of the Armada driver (Yuho Choi)Link: https://lore.kernel.org/lkml/75feea31-683d-45a1-87f4-ab045e0152ae@oss.qualcomm.com List of files: /linux/fs/ext4/hash-test.c

3147cac6c1929f26b4687993b8c7af5b7b34496d - ext4: add Kunit coverage for directory hash computation

Sun, 31 May 2026 10:00:18 +0200

ext4: add Kunit coverage for directory hash computationIntroduce Kunit tests for fs/ext4/hash.c to verify ext4fs_dirhash()across the legacy, half-MD4, and TEA hash variants.The tests cover empty, seeded hashing, and non-ASCII name handling.They also verify error paths, including invalid hash versions andSipHash without a configured key, and check that the signed andunsigned hash variants differ on non-ASCII input as expected.When CONFIG_UNICODE is enabled, the tests further verify casefolded-namehashing and the fallback behavior for invalid input.Co-developed-by: Chen Hao Yu Signed-off-by: Chen Hao Yu Signed-off-by: Guan-Chun Wu <409411716@gms.tku.edu.tw>Link: https://patch.msgid.link/20260531080019.3794809-2-409411716@gms.tku.edu.twSigned-off-by: Theodore Ts'o List of files: /linux/fs/ext4/hash-test.c
