From d8b7b3fa9f9b2dc67fa1df29c4ce98eb10d62824 Mon Sep 17 00:00:00 2001 From: Yinan Zhang Date: Fri, 1 Apr 2022 11:28:48 -0700 Subject: tools/vm/page_owner_sort.c: remove -c option The -c option is used to cull by stacktrace. Now, --cull option has been Added in page_owner_sort.c. Culling by stacktrace is one of the function of "--cull". No need to set an extra parameter. So remove -c option. Remove parsing of -c when parse parameter and remove "-c" from usage.
