  "message": "devscgroup: make white list more compact in some cases\n\nConsider you added a \u0027c foo:bar r\u0027 permission to some cgroup and then (a\nbit later) \u0027c\u0027foo:bar w\u0027 for it.  After this you\u0027ll see the\n\nc foo:bar r\nc foo:bar w\n\nlines in a devices.list file.\n\nAnother example - consider you added 10 \u0027c foo:bar r\u0027 permissions to some\ncgroup (e.g.  by mistake).  After this you\u0027ll see 10 c foo:bar r lines in\na list file.\n\nThis is weird.  This situation also has one more annoying consequence.\nHaving many items in a white list makes permissions checking slower, sine\nit has to walk a longer list.\n\nThe proposal is to merge permissions for items, that correspond to the\nsame device.\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
