Subject: [lustre-devel] [PATCH 05/37] lustre: obd_type: use typ_kobj.name as typ_name
Date: Tue, 19 Feb 2019 11:09:05 +1100 [thread overview]
Message-ID: <155053494507.24125.1847979512182217144.stgit@noble.brown> (raw)
In-Reply-To: <155053473693.24125.6976971762921761309.stgit@noble.brown>
As the kobject has a name (after kobject_add has been called),
we don't need to also store it in typ_name.
So use typ_kobj.name instead of typ_name.
This requires changing some "char *" to "const char *" as
typ.kobj.name is const.
