[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.

[PATCH openEuler-1.0-LTS] ACPI: battery: Fix possible crash when unregistering a battery hook
by Heyuan Wang 24 Dec '24

24 Dec '24

From: Armin Wolf <W_Armin(a)gmx.de> stable inclusion from stable-v4.19.323 commit 76fb2cbf01571926da8ecf6876cc8cb07d3f5183 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBBN6V Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------------------- [ Upstream commit 76959aff14a0012ad6b984ec7686d163deccdc16 ] When a battery hook returns an error when adding a new battery, then the battery hook is automatically unregistered. However the battery hook provider cannot know that, so it will later call battery_hook_unregister() on the already unregistered battery hook, resulting in a crash. Fix this by using the list head to mark already unregistered battery hooks as already being unregistered so that they can be ignored by battery_hook_unregister().
