>From c257cb67ce00c8769730cfa92379a53009d99b28 Mon Sep 17 00:00:00 2001 From: serue@xxxxxxxxxx <serue@xxxxxxxxxx> Date: Wed, 5 Dec 2007 14:02:45 -0800 Subject: [RFC] [PATCH -mm] reiser4: replace uid==0 check with capability Reiser4 gives root some reserved blocks. Replace the uid==0 check, which is not safe in the face of user namespaces, with a CAP_SYS_RESOURCE check, which seems appropriate. The per-uid and per-guid reservations appear unimplemented so I'm ignoring them.
