Subject: [PATCH 09/15] IB/hfi1: Use filedata rather than filepointer
Date: Tue, 02 May 2017 17:41:54 -0700 [thread overview]
Message-ID: <20170503004152.6965.51090.stgit@scvm10.sc.intel.com> (raw)
In-Reply-To: <20170503003734.6965.67405.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org>
From: Michael J. Ruhl <michael.j.ruhl-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
Since almost all functions that use the hfi1_filedata get the pointer
from the file pointer, simplify by only passing the hfi1_filedata pointer.
