…onfig WB5, WB6 defconfigs: Remove CONFIG_SMP - kernel default is off. WB6: Add CONFIG_GPIO_MXC, CONFIG_GPIO_GENERIC_PLATFORM. CONFIG_GPIO_MXC changed from def_bool y to tristate "i.MX GPIO support". Default value is now false. Change it to 'y' in imx6_wirenboard_defconfig. Cleanup via savedefconfig. arch/arm/configs: *defconfig: Enable CONFIG_PINCTRL_MCP23S08=m arch/arm/configs: *defconfig: Enable CONFIG_MCP4728=m TODO: Debug. WB5, WB6: Enable AD5064/LTC2637 and MCP4728 in-kernel. На ядре 5.8.9 не выполняется автоматическая загрузка драйверов i2c, если они разрешены как модули, причину надо найти. Временное решение - разрешить их как часть ядра. Помогает также ручной вызов modprobe, если он идет перед probe контроллера i2c. CONFIG_AD5064=y CONFIG_MCP4728=y arch/arm/configs: WB5, WB6 defconfig: enable CONFIG_LEDS_TRIGGER_DEFAULT_OFF=y add rtl8xxxu to defconfig file (cherry picked from commit 192e6ef) (cherry picked from commit b72550c) arch/arm/configs: WB5, WB6 defconfig: Add CONFIG_OF_CONFIGFS=y Enable configfs overlays. wb6: enable full 1G/3G memory split for 1GB models arch/arm/configs: WB5, WB6 defconfig: Enable CONFIG_RTL8723BU=m CONFIG_NVMEM_IMX_OCOTP=y LIRC and SC16IS7XX are included into wb6 defconfig wb7: initial defconfig ARM: config: wb7: disable graphics and unused drivers wb7: add defconfig for initramfs wb6, wb7: added rtc-rv8803 driver to defconfig (#84) * wb6, wb7: added rtc-rv8803 driver to defconfig as a module wb6: fix bootlet configuration and MMC pinctrl config (#89) This commit fixes USB bootlet kernel: - fix kernel panic on g_mass_storage module removing by making configfs included (not as module); - fix LEDs by enabling PWM driver for i.MX6 Also it adds missing eMMC lanes pinctrls. Looks like it worked earlier because Boot ROM initialized these pins (didn't work on USB boot though). wb7: add missing drivers similar to wb6 (#90) fec: use ethFECX interface names to reorder them in userspace (#97) Interface name swapping (eth0<->eth1) is broken in Debian bullseye because of the missing systemd patch from Debian maintainers (which was available in stretch). Ethernet interfaces enumeration is performed in the order they are defined in the device tree. For imx6ul, FEC2 goes before FEC1. Instead of changing the order in the device tree (in common file for many device trees), we decided to change the interface name template in FEC driver from ethX to ethFECX. This feature can be disabled in the kernel config. wb7: enable SYSVIPC config option (#98) This config option enables System V IPC functions (like shared memory access, semaphores, message queues and so on). As it turned out, these functions are used by some of our customers. wb: add AF_KCM option to enable Docker on Debian 11 add bunch of config options for Docker as suggested by ./check-config.sh also enable wireguard and bonding core network drivers wb: Kconfig: add modules for ipsec support (#117) * wb: Kconfig: add modules for ipsec support * Extended netfilter support (#118) * add nftables to changelog Co-authored-by: KraPete <86825564+KraPete@users.noreply.github.com> wb7-initramfs: remove all unused USB gadget features (#123) wb6_defconfig: add nft nat support (#126) wb: adddefconfig for SoM testing defconfig: wb7 mdio bitbang defconfig: wb7: enable exfat support (module) in defconfig defconfig: add wb7min defconfig minimum configuration w/o Wi-Fi and with everything compiled in kernel. wb6: initramfs: add missing GPIO driver to defconfig + actualize defconfig: wb7: add wbec drivers ARM: config: wb7: add wbec and SD3078 drivers, remove AXP pwrkey driver defconfig: wb7: enable rtl8733bu fix defconfig: add wb7min defconfig

To fix this issue, let's use change f2fs_stat_lock lock type from raw_spinlock_t to spinlock_t, it's safe due to: - we don't need to use raw version of spinlock as the path is not performance sensitive. - we don't need to use irqsave version of spinlock as it won't be used in irq context. Quoted from [1]: "Extend lockdep to validate lock wait-type context. The current wait-types are: LD_WAIT_FREE, /* wait free, rcu etc.. */ LD_WAIT_SPIN, /* spin loops, raw_spinlock_t etc.. */ LD_WAIT_CONFIG, /* CONFIG_PREEMPT_LOCK, spinlock_t etc.. */ LD_WAIT_SLEEP, /* sleeping locks, mutex_t etc.. */ Where lockdep validates that the current lock (the one being acquired) fits in the current wait-context (as generated by the held stack). This ensures that there is no attempt to acquire mutexes while holding spinlocks, to acquire spinlocks while holding raw_spinlocks and so on. In other words, its a more fancy might_sleep()."
