hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBBN6V CVE: NA -------------------------------- Because commit a787e5400a1c ("driver core: add device probe log helper") was not merge, msg format is different from stable, which causes compile error. Adapt msg to fix it. Fixes: 24564bb891ae ("ACPI: PMIC: Remove unneeded check in tps68470_pmic_opregion_probe()") Signed-off-by: Qi Xi <xiqi2(a)huawei.com> --- drivers/acpi/pmic/tps68470_pmic.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/acpi/pmic/tps68470_pmic.c b/drivers/acpi/pmic/tps68470_pmic.c index fde8a1271c9b..564215948b59 100644 --- a/drivers/acpi/pmic/tps68470_pmic.c +++ b/drivers/acpi/pmic/tps68470_pmic.c @@ -376,8 +376,10 @@ static int tps68470_pmic_opregion_probe(struct platform_device *pdev) struct tps68470_pmic_opregion *opregion; acpi_status status; - if (!tps68470_regmap) - return dev_err_probe(dev, -EINVAL, "regmap is missing\n"); + if (!tps68470_regmap) { + dev_warn(dev, "dev or regmap is NULL\n"); + return -EINVAL; + } if (!handle) { dev_warn(dev, "acpi handle is NULL\n"); -- 2.33.0

[PATCH OLK-5.10 v2 000/133] erofs: add ondemand mode support
by Baokun Li 25 Dec '24

25 Dec '24

Changes since v1: * Corrected patch header format. This patch set enables erofs/fscache/cachefiles to support ondemand mode, including readahead, domain sharing, failover, etc. In addition to patches from the open source community, we have made some compatibility modifications and quality hardening for this feature: * Added the dynamic switches of erofs_enabled and cachefiles_ondemand_enabled. * The structure of the cache file directory is modified to be the same as that of the mainline to prevent the problem that the existing cache cannot be found due to kernel upgrade and downgrade. * Use the same xattr as that in the mainline to prevent cache failure caused by kernel upgrade or downgrade. * Various bugfixes...

[PATCH openEuler-1.0-LTS] dhugetlb: keep refcount to 0 while page is actually free in pool
by Liu Shixin 24 Dec '24

24 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBDF90 -------------------------------- While we split/merge page in dynamic pool, the refcount of page may be increased to 1 due to prep_new_page(), and we then set the refcount to 0. That means there's a time window that the refcount of the free page is not 0. split_huge_pages_set() will scan all pages and try to get the refcount If try to get refcount in the above time window and put_page() after the refcount is set to 0, the refcount will be decreased to -1. It's dangerous if the refcount for page is not 0 when split/merge, so try not to get refcount there.
