| Subject: Documentation/vm/page_owner.rst: fix comments |
| |
| There are some comments that need to be fixed. |
| |
| Thanks for Shuah Khan's constructive suggestions. The comments have been |
| fixed as follows. |
| |
| a. So, if you'd like to use it, you need |
| to add "page_owner=on" into your boot cmdline. |
| |
| Here, "into" has been replaced with "to". |
| |
| b. ...page owner is disabled in runtime due to no |
| enabling, boot option, runtime overhead is marginal. |
| |
| Here, "no" has been replaced with "not". |
