From bd4660d49ac64886fb27649138e52d81be161fee Mon Sep 17 00:00:00 2001 From: Christian Schoenebeck Date: Tue, 4 Oct 2022 22:54:09 +0200 Subject: [PATCH] tests/9p: merge v9fs_tlcreate() and do_lcreate() As with previous patches, unify those 2 functions into a single function v9fs_tlcreate() by using a declarative function arguments approach.
