zhouyuhang fa0122eaca selftests/mount_setattr: fix idmap_mount_tree_invalid failed to run ... Test case idmap_mount_tree_invalid failed to run on the newer kernel with the following output: # RUN mount_setattr_idmapped.idmap_mount_tree_invalid ... # mount_setattr_test.c:1428:idmap_mount_tree_invalid:Expected sys_mount_setattr(open_tree_fd, "", AT_EMPTY_PATH, &attr, sizeof(attr)) (0) ! = 0 (0) # idmap_mount_tree_invalid: Test terminated by assertion This is because tmpfs is mounted at "/mnt/A", and tmpfs already contains the flag FS_ALLOW_IDMAP after the commit 7a80e5b8c6 ("shmem: support idmapped mounts for tmpfs"). So calling sys_mount_setattr here returns 0 instead of -EINVAL as expected. Ramfs does not support idmap mounts, so we can use it here to test invalid mounts, which allows the test case to pass with the following output: # Starting 1 tests from 1 test cases. # RUN mount_setattr_idmapped.idmap_mount_tree_invalid ... # OK mount_setattr_idmapped.idmap_mount_tree_invalid ok 1 mount_setattr_idmapped.idmap_mount_tree_invalid # PASSED: 1 / 1 tests passed.
