Hi Tejun,
After merging the slabh tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
drivers/misc/hwlat_detector.c: In function 'debug_sample_fread':
drivers/misc/hwlat_detector.c:713: error: implicit declaration of function 'kzalloc'
drivers/misc/hwlat_detector.c:713: warning: assignment makes pointer from integer without a cast
drivers/misc/hwlat_detector.c:755: error: implicit declaration of function 'kfree'
Caused by commit d103d3b3e8512312b5254950035366d4422a479a ("percpu: don't
implicitly include slab.h from percpu.h") from the slabh tree interacting
with commit 94366eaeaf5ac4831637de39eac48ca62afe4e2a ("hwlat_detector: A
system hardware latency detector") from the hwlat tree.
I applied the following merge fixup which should be applied to the hwlat
tree anyway, please Jon (see Documentation/SubmitChecklist Rule #1 :-))?
