Now that sysfs has the deadlock race fixed with module removal, enable the deadlock tests module removal tests. They were left disabled by default as otherwise you would deadlock your system ./tools/testing/selftests/sysfs/sysfs.sh -t 0027 Running test: sysfs_test_0027 - run #0 Test for possible rmmod deadlock while writing x ... ok ./tools/testing/selftests/sysfs/sysfs.sh -t 0028 Running test: sysfs_test_0028 - run #0 Test for possible rmmod deadlock using rtnl_lock while writing x ... ok Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> --- tools/testing/selftests/sysfs/sysfs.sh | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
