Subject: llist: make locking comments consistent
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=25c786a9f7f8b5e882367f569020f1f37ac9fea7;p=thirdparty%2Flinux.git

llist: make locking comments consistent

llist's locking requirement table has a legend which claims that all
operations not needing a lock a marked with '-', whereas in truth for some
table entries just a whitespace is used.

Add the '-' to all appropriate places.
