Subject: [PATCH 03/21] staging: lustre: remove linux-curproc.c
Date: Tue, 20 Feb 2018 13:23:37 +1100 [thread overview]
Message-ID: <151909341763.25814.2230821270457016452.stgit@noble> (raw)
In-Reply-To: <151909308778.25814.9912662268627044409.stgit@noble>
The only functionality remaining here is
cfs_curproc_cap_pack(),
and it can be trivially implemented as an inline
in curproc.h.
So do that and remove the file.
