[PATCH v6 1/2] selftests: vm: bring common functions to a new file

by Muhammad Usama Anjum

Bring common functions to a new file while keeping code as much same as possible. These functions can be used in the new tests. This helps in avoiding code duplication. Signed-off-by: Muhammad Usama Anjum <usama.anjum(a)collabora.com> --- Changes in V6: - Correct header files inclusion Changes in V5: Keep moved code as same as possible - Updated macros names - Removed macro used to show bit number of dirty bit, added a comment instead - Corrected indentation --- tools/testing/selftests/vm/Makefile | 7 +- tools/testing/selftests/vm/madv_populate.c | 34 +----- .../selftests/vm/split_huge_page_test.c | 79 +------------ tools/testing/selftests/vm/vm_util.c | 108 ++++++++++++++++++ tools/testing/selftests/vm/vm_util.h | 9 ++ 5 files changed, 124 insertions(+), 113 deletions(-) create mode 100644 tools/testing/selftests/vm/vm_util.c create mode 100644 tools/testing/selftests/vm/vm_util.h diff --git a/tools/testing/selftests/vm/Makefile b/tools/testing/selftests/vm/Makefile index 5e43f072f5b76..4e68edb26d6b6 100644 --- a/tools/testing/selftests/vm/Makefile +++ b/tools/testing/selftests/vm/Makefile @@ -34,7 +34,7 @@ TEST_GEN_FILES += hugepage-mremap TEST_GEN_FILES += hugepage-shm TEST_GEN_FILES += hugepage-vmemmap TEST_GEN_FILES += khugepaged -TEST_GEN_FILES += madv_populate +TEST_GEN_PROGS = madv_populate TEST_GEN_FILES += map_fixed_noreplace TEST_GEN_FILES += map_hugetlb TEST_GEN_FILES += map_populate @@ -47,7 +47,7 @@ TEST_GEN_FILES += on-fault-limit TEST_GEN_FILES += thuge-gen TEST_GEN_FILES += transhuge-stress TEST_GEN_FILES += userfaultfd -TEST_GEN_FILES += split_huge_page_test +TEST_GEN_PROGS += split_huge_page_test TEST_GEN_FILES += ksm_tests ifeq ($(MACHINE),x86_64) @@ -91,6 +91,9 @@ TEST_FILES := test_vmalloc.sh KSFT_KHDR_INSTALL := 1 include ../lib.mk +$(OUTPUT)/madv_populate: vm_util.c +$(OUTPUT)/split_huge_page_test: vm_util.c + ifeq ($(MACHINE),x86_64) BINARIES_32 := $(patsubst %,$(OUTPUT)/%,$(BINARIES_32)) BINARIES_64 := $(patsubst %,$(OUTPUT)/%,$(BINARIES_64)) diff --git a/tools/testing/selftests/vm/madv_populate.c b/tools/testing/selftests/vm/madv_populate.c index 3ee0e82756002..715a42e8e2cdb 100644 --- a/tools/testing/selftests/vm/madv_populate.c +++ b/tools/testing/selftests/vm/madv_populate.c @@ -18,6 +18,7 @@ #include <sys/mman.h> #include "../kselftest.h" +#include "vm_util.h" /* * For now, we're using 2 MiB of private anonymous memory for all tests. @@ -26,18 +27,6 @@ static size_t pagesize;

[PATCH v1] selftests/landlock: Fix out-of-tree builds

by Mickaël Salaün

These changes simplify the Makefile and handle these 5 ways to build Landlock tests: - make -C tools/testing/selftests/landlock - make -C tools/testing/selftests TARGETS=landlock gen_tar - make TARGETS=landlock kselftest-gen_tar - make TARGETS=landlock O=build kselftest-gen_tar - make -C /tmp/linux TARGETS=landlock O=/tmp/build kselftest-gen_tar This also makes $(KHDR_INCLUDES) available to other test collections when building in their directory.

[PATCH net-next] selftests/bonding: re-add lladdr target test

by Matthieu Baerts

It looks like this test has been accidentally dropped when resolving conflicts in this Makefile. Most probably because there were 3 different patches modifying this file in parallel: commit 152e8ec77640 ("selftests/bonding: add a test for bonding lladdr target") commit bbb774d921e2 ("net: Add tests for bonding and team address list management") commit 2ffd57327ff1 ("selftests: bonding: cause oops in bond_rr_gen_slave_id") The first one was applied in 'net-next' while the two other ones were recently applied in the 'net' tree. But that's alright, easy to fix by re-adding the missing one!

[PATCH] selftests/livepatch: normalize sysctl error message

by Joe Lawrence

The livepatch kselftests rely on comparing expected and actual output from such commands as sysctl. A recent commit in procps-ng v4.0.0 [1] changed sysctl's output to emit key pathnames like: sysctl: setting key "/proc/sys/kernel/ftrace_enabled": Device or resource busy versus previous dotted output: sysctl: setting key "kernel.ftrace_enabled": Device or resource busy The modification in output was later reverted [2], but since the change has been tagged in procps-ng v4.0.0, update the livepatch kselftest to handle either case.

Zwiększenie płynności finansowej

by Jakub Olejniczak

Dzień dobry, kontaktuję się z Państwem, ponieważ chciałbym zaproponować wygodne rozwiązanie, które umożliwi Państwa firmie stabilny rozwój. Konkurencyjne otoczenie wymaga ciągłego ulepszania i poszerzenia oferty, co z kolei wiąże się z koniecznością inwestowania. Brak odpowiedniego kapitału poważnie ogranicza tempo rozwoju firmy. Od wielu lat z powodzeniem pomagam firmom w uzyskaniu najlepszej formy finansowania z banku oraz UE. Mam stałych Klientów, którzy nadal chętnie korzystają z moich usług, a także polecają je innym. Czy chcieliby Państwo skorzystać z pomocy wykwalifikowanego i doświadczonego doradcy finansowego? Pozdrawiam Jakub Olejniczak
