[PATCH] lib: PRIME_NUMBERS_KUNIT_TEST should not select PRIME_NUMBERS

by Geert Uytterhoeven

Enabling a (modular) test should not silently enable additional kernel functionality, as that may increase the attack vector of a product. Fix this by making PRIME_NUMBERS_KUNIT_TEST depend on PRIME_NUMBERS instead of selecting it. After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to build modules for all appropriate tests for ones system, without pulling in extra unwanted functionality, while still allowing a tester to manually enable PRIME_NUMBERS and this test suite on a system where PRIME_NUMBERS is not enabled by default.

[PATCH AUTOSEL 5.10 08/11] selftests/mincore: Allow read-ahead pages to reach the end of the file

by Sasha Levin

From: Qiuxu Zhuo <qiuxu.zhuo(a)intel.com> [ Upstream commit 197c1eaa7ba633a482ed7588eea6fd4aa57e08d4 ] When running the mincore_selftest on a system with an XFS file system, it failed the "check_file_mmap" test case due to the read-ahead pages reaching the end of the file. The failure log is as below: RUN global.check_file_mmap ... mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024) mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file check_file_mmap: Test failed FAIL global.check_file_mmap This is because the read-ahead window size of the XFS file system on this machine is 4 MB, which is larger than the size from the #PF address to the end of the file. As a result, all the pages for this file are populated. blockdev --getra /dev/nvme0n1p5 8192 blockdev --getbsz /dev/nvme0n1p5 512 This issue can be fixed by extending the current FILE_SIZE 4MB to a larger number, but it will still fail if the read-ahead window size of the file system is larger enough. Additionally, in the real world, read-ahead pages reaching the end of the file can happen and is an expected behavior. Therefore, allowing read-ahead pages to reach the end of the file is a better choice for the "check_file_mmap" test case.
