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 ... --- drivers/md/bcache/features.c | 75 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 75 insertions(+) create mode 100644 drivers/md/bcache/features.c (limited to 'drivers/md/bcache/features.c') diff --git a/drivers/md/bcache/features.c b/drivers/md/bcache/features.c new file mode 100644 index 000000000..634922c56 --- /dev/null +++ b/drivers/md/bcache/features.c @@ -0,0 +1,75 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Feature set bits and string conversion. + * Inspired by ext4's features compat/incompat/ro_compat related code. + * + * Copyright 2020 Coly Li + * + */ +#include "bcache_ondisk.h" +#include "bcache.h" +#include "features.h" + +struct feature { + int compat; + unsigned int mask; + const char *string; +}; + +static struct feature feature_list[] = { + {BCH_FEATURE_INCOMPAT, BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE, + "large_bucket"}, + {0, 0, NULL }, +}; + +#define compose_feature_string(type) \ +({ \ + struct feature *f; \ + bool first = true; \ + \ + for (f = &feature_list[0]; f->compat != 0; f++) { \ + if (f->compat != BCH_FEATURE_ ## type) \ + continue; \ + if (BCH_HAS_ ## type ## _FEATURE(&c->cache->sb, f->mask)) { \ + if (first) { \ + out += snprintf(out, buf + size - out, \ + "["); \ + } else { \ + out += snprintf(out, buf + size - out, \ + " ["); \ + } \ + } else if (!first) { \ + out += snprintf(out, buf + size - out, " "); \ + } \ + \ + out += snprintf(out, buf + size - out, "%s", f->string);\ + \ + if (BCH_HAS_ ## type ## _FEATURE(&c->cache->sb, f->mask)) \ + out += snprintf(out, buf + size - out, "]"); \ + \ + first = false; \ + } \ + if (!first) \ + out += snprintf(out, buf + size - out, "\n"); \ +}) + +int bch_print_cache_set_feature_compat(struct cache_set *c, char *buf, int size) +{ + char *out = buf; + compose_feature_string(COMPAT); + return out - buf; +} + +int bch_print_cache_set_feature_ro_compat(struct cache_set *c, char *buf, int size) +{ + char *out = buf; + compose_feature_string(RO_COMPAT); + return out - buf; +} + +int bch_print_cache_set_feature_incompat(struct cache_set *c, char *buf, int size) +{ + char *out = buf; + compose_feature_string(INCOMPAT); + return out - buf; +} -- cgit v1.3.1
