HEAD: 9026e820cbd2ea39a06a129ecdddf2739bd3602b fs/signalfd: fix build error for BUS_MCEERR_AR

From: Randy Dunlap <rdunlap@infradead.org> Date: Mon, 12 Feb 2018 13:18:38 -0800 Subject: [PATCH] fs/signalfd: fix build error for BUS_MCEERR_AR
Fix build error in fs/signalfd.c by using same method that is used in kernel/signal.c: separate blocks for different signal si_code values.
./fs/signalfd.c: error: 'BUS_MCEERR_AR' undeclared (first use in this function)
