------------------------------------------------------ From: John Sperbeck jsperbeck@google.com Subject: mm: memcg: declare do_memsw_account inline Date: Thu, 28 Nov 2024 12:39:59 -0800
In commit 66d60c428b23 ("mm: memcg: move legacy memcg event code into memcontrol-v1.c"), the static do_memsw_account() function was moved from a .c file to a .h file. Unfortunately, the traditional inline keyword wasn't added. If a file (e.g., a unit test) includes the .h file, but doesn't refer to do_memsw_account(), it will get a warning like:
mm/memcontrol-v1.h:41:13: warning: unused function 'do_memsw_account' [-Wunused-function] 41 | static bool do_memsw_account(void) | ^~~~~~~~~~~~~~~~
