From cf9610f9116d55c5a66ef9f1faecacabd93a9322 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 24 Aug 2026 08:46:03 -0700 Subject: Merge tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Core changes: - Use the non-blocking mux_state_try_select() in the generic MUX pin control back-end - Free pin maps on pinctrl_generic_to_map() failure in the core helpers New hardware pin control: - Qualcomm Maili TLMM SoC, PMG1110 PMIC, and Eliza LPASS LPI TLMM SoC (this is for the low power audio, LPASS = Low Power Audio SubSystem portions) - Upboard support on top of the Intel pin controller - Apple T6030 and T6031 support (just compatible strings) - Samsung Exynos 8855 SoC - Mediatek MT6858 SoC - Rockchip RK3308B and RV1106 SoCs - Airoha EN7523 and AN7563 SoCs Improvements: - Qualcomm TLMM GPIOs are unconditionally marked as wakeup capable - Qualcomm improvements on top of the Qualcomm PDC (power domain controller) irqchip improvements from tglx:s tree - Qualcomm IPQ806x and IPQ9650 non-urgent pin grop fixups - The NPCM8xx driver has been put into shape fixing many pin and group definitions - Some non-urgent Tegra 264 pin assignments are fixed up - Some non-urgent fixups to Airoha AN7581 and AN7583 registers and pin assignments, missing features etc" * tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (130 commits) dt-bindings: pinctrl: Convert TI DA850 pupd to DT schema pinctrl: meson: sync some modify from A4 pinctrl: meson: a4: Add input enable pin configuration pinctrl: realtek: rtd1625: remove unused group name spdif_sel pinctrl: realtek: rtd1625: fix base_bit for VE4 GPIO 13 dt-bindings: pinctrl: microchip,pic32mzda-pinctrl: Convert to DT schema Revert "Merge branch 'ib-rsk7204' into devel" pinctrl: rockchip: Add RV1106 pinctrl support dt-bindings: pinctrl: rockchip: Add RV1106 compatible pinctrl: rockchip: Decode drive strength in the get function pinctrl: fix PINCTRL_GENERIC_MUX not always being selectable pinctrl: airoha: add support of an7563 SoC dt-bindings: pinctrl: airoha: add support of an7563 pin controller pinctrl: airoha: try to find chip scu node by phandle first pinctrl: airoha: add support of en7523 SoC dt-bindings: pinctrl: airoha: add support of en7523 pin controller pinctrl: airoha: an7583: add support for olt pinmux pinctrl: airoha: an7583: add support for pon_alt pinmux pinctrl: airoha: an7583: add support for npu_uart pinmux dt-bindings: pinctrl: airoha: an7583: add missed features ... --- fs/pnode.h | 65 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 fs/pnode.h (limited to 'fs/pnode.h') diff --git a/fs/pnode.h b/fs/pnode.h new file mode 100644 index 000000000..b029db225 --- /dev/null +++ b/fs/pnode.h @@ -0,0 +1,65 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ +/* + * linux/fs/pnode.h + * + * (C) Copyright IBM Corporation 2005. + */ +#ifndef _LINUX_PNODE_H +#define _LINUX_PNODE_H + +#include +#include "mount.h" + +#define IS_MNT_SHARED(m) ((m)->mnt_t_flags & T_SHARED) +#define IS_MNT_SLAVE(m) ((m)->mnt_master) +#define IS_MNT_NEW(m) (!(m)->mnt_ns) +#define CLEAR_MNT_SHARED(m) ((m)->mnt_t_flags &= ~T_SHARED) +#define IS_MNT_UNBINDABLE(m) ((m)->mnt_t_flags & T_UNBINDABLE) +#define IS_MNT_MARKED(m) ((m)->mnt_t_flags & T_MARKED) +#define SET_MNT_MARK(m) ((m)->mnt_t_flags |= T_MARKED) +#define CLEAR_MNT_MARK(m) ((m)->mnt_t_flags &= ~T_MARKED) +#define IS_MNT_LOCKED(m) ((m)->mnt.mnt_flags & MNT_LOCKED) + +#define CL_EXPIRE 0x01 +#define CL_SLAVE 0x02 +#define CL_COPY_UNBINDABLE 0x04 +#define CL_MAKE_SHARED 0x08 +#define CL_PRIVATE 0x10 +#define CL_COPY_MNT_NS_FILE 0x40 + +/* + * EXCL[namespace_sem] + */ +static inline void set_mnt_shared(struct mount *mnt) +{ + mnt->mnt_t_flags &= ~T_SHARED_MASK;
