Subject: [Resource Leak] Missing closing files in tools/bpf/bpf_asm.c

Dear Kernel maintainers,

          1. In ksm_read_sysfs, the file opened at Line 74 may not closed when going to Line 83.
          Location: https://github.com/torvalds/linux/blob/512b7931ad0561ffe14265f9ff554a3c081b476b/tools/testing/selftests/vm/ksm_tests.c#L74-L83

         2. In ksm_write_sysfs, the file opened at Line 56 may not closed when going to Line 64.
         Location: https://github.com/torvalds/linux/blob/512b7931ad0561ffe14265f9ff554a3c081b476b/tools/testing/selftests/vm/ksm_tests.c#L55-L65

           Should they be bugs? I can send a patch for these.

Best,
Ryan
