Subject: [PATCH][next] apparmor: remove useless static inline function is_deleted
Date: Mon,  4 Mar 2024 16:36:55 +0000	[thread overview]
Message-ID: <20240304163655.771616-1-colin.i.king@gmail.com> (raw)

The inlined function is_deleted is redundant, it is not called at all
from any function in security/apparmor/file.c and so it can be removed.

Cleans up clang scan build warning:
security/apparmor/file.c:153:20: warning: unused function
'is_deleted' [-Wunused-function]
