From bd2a31d522344b3ac2fb680bd2366e77a9bd8209 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 4 Mar 2014 14:54:22 -0500 Subject: get rid of fget_light() instead of returning the flags by reference, we can just have the low-level primitive return those in lower bits of unsigned long, with struct file * derived from the rest.
