Subject: selftests: efivarfs: remove the test_create_read file if it was exist
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f8a0590f0e01402873ec28a0da46f979f6bc56f1;p=linux.git

selftests: efivarfs: remove the test_create_read file if it was exist

After the first run, the test case 'test_create_read' will always
fail because the file is exist and file's attr is 'S_IMMUTABLE',
open with 'O_RDWR' will always return -EPERM.
