But # currently, the kernel returns '-EEXIST' if we try to register without # uregistering it first. This could expose the system to racing issues # while unregistering and registering FADump from userspace during udev # events. Spare the userspace of this and let it be taken care of in the # kernel space for a simpler interface. # # Since this change, running 'echo 1 > /sys/kernel/fadump_registered' # would result in re-regisering (unregistering and registering) FADump, # if it was already registered. # # Signed-off-by: Hari Bathini # Acked-by: Mahesh Salgaonkar # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 0823c68b054bca9dc321adea829af5cf36afb30b # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_rainier_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/rainier_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_rainier_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x479960) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.19.0-rc3-g0823c68b054bc Created: Thu Sep 20 02:52:45 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2289117 Bytes = 2235.47 KiB = 2.18 MiB Load Address: 00500000 Entry Point: 00501104 Completed OK # rm -rf /kisskb/build/powerpc-next_44x_rainier_defconfig_powerpc-gcc5 # Build took: 0:00:16.328689
