[PATCH AUTOSEL 5.15 10/36] selftests/zram: Adapt the situation that /dev/zram0 is being used

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit 01dabed20573804750af5c7bf8d1598a6bf7bf6e ] If zram-generator package is installed and works, then we can not remove zram module because zram swap is being used. This case needs a clean zram environment, change this test by using hot_add/hot_remove interface. So even zram device is being used, we still can add zram device and remove them in cleanup. The two interface was introduced since kernel commit 6566d1a32bf7("zram: add dynamic device add/remove functionality") in v4.2-rc1. If kernel supports these two interface, we use hot_add/hot_remove to slove this problem, if not, just check whether zram is being used or built in, then skip it on old kernel.

[PATCH AUTOSEL 5.15 09/36] selftests/zram01.sh: Fix compression ratio calculation

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit d18da7ec3719559d6e74937266d0416e6c7e0b31 ] zram01 uses `free -m` to measure zram memory usage. The results are no sense because they are polluted by all running processes on the system. We Should only calculate the free memory delta for the current process. So use the third field of /sys/block/zram<id>/mm_stat to measure memory usage instead. The file is available since kernel 4.1. orig_data_size(first): uncompressed size of data stored in this disk. compr_data_size(second): compressed size of data stored in this disk mem_used_total(third): the amount of memory allocated for this disk Also remove useless zram cleanup call in zram_fill_fs and so we don't need to cleanup zram twice if fails.

[PATCH AUTOSEL 5.15 05/36] kselftest: signal all child processes

by Sasha Levin

From: Li Zhijian <lizhijian(a)cn.fujitsu.com> [ Upstream commit 92d25637a3a45904292c93f1863c6bbda4e3e38f ] We have some many cases that will create child process as well, such as pidfd_wait. Previously, we will signal/kill the parent process when it is time out, but this signal will not be sent to its child process. In such case, if child process doesn't terminate itself, ksefltest framework will hang forever. Here we group all its child processes so that kill() can signal all of them in timeout.

[PATCH AUTOSEL 5.15 04/36] selftests: rtc: Increase test timeout so that all tests run

by Sasha Levin

From: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> [ Upstream commit f034cc1301e7d83d4ec428dd6b8ffb57ca446efb ] The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

[PATCH AUTOSEL 5.15 03/36] kunit: tool: Import missing importlib.abc

by Sasha Levin

From: Michał Winiarski <michal.winiarski(a)intel.com> [ Upstream commit 235528072f28b3b0a1446279b7eaddda36dbf743 ] Python 3.10.0 contains: 9e09849d20 ("bpo-41006: importlib.util no longer imports typing (GH-20938)") It causes importlib.util to no longer import importlib.abs, which leads to the following error when trying to use kunit with qemu: AttributeError: module 'importlib' has no attribute 'abc'.
