[PATCH openEuler-1.0-LTS] cpuidle: Fix kobject memory leaks in error paths
by Xia Fukun 22 Sep '23

22 Sep '23

From: Anel Orazgaliyeva <anelkz(a)amazon.de> stable inclusion from stable-v4.19.294 commit 22d44652b6d6404b96a40bb051d1046e6c005ae5 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I81G0T CVE: NA -------------------------------- [ Upstream commit e5f5a66c9aa9c331da5527c2e3fd9394e7091e01 ] Commit c343bf1ba5ef ("cpuidle: Fix three reference count leaks") fixes the cleanup of kobjects; however, it removes kfree() calls altogether, leading to memory leaks. Fix those and also defer the initialization of dev->kobj_dev until after the error check, so that we do not end up with a dangling pointer.

[PATCH OLK-5.10] ext4: do not mark inode dirty every time when appending using delalloc
by WoZ1zh1 20 Sep '23

20 Sep '23

From: Liu Song <liusong(a)linux.alibaba.com> mainline inclusion from mainline-v6.6-rc1 commit 03de20bed203b0819225d4de98353c1f8755a1dd category: perf bugzilla: https://gitee.com/openeuler/kernel/issues/I82QPS CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In the delalloc append write scenario, if inode's i_size is extended due to buffer write, there are delalloc writes pending in the range up to i_size, and no need to touch i_disksize since writeback will push i_disksize up to i_size eventually. Offers significant performance improvement in high-frequency append write scenarios. I conducted tests in my 32-core environment by launching 32 concurrent threads to append write to the same file. Each write operation had a length of 1024 bytes and was repeated 100000 times. Without using this patch, the test was completed in 7705 ms. However, with this patch, the test was completed in 5066 ms, resulting in a performance improvement of 34%. Moreover, in test scenarios of Kafka version 2.6.2, using packet size of 2K, with this patch resulted in a 10% performance improvement.
