Hi Tejun,
After merging the slabh tree, today's linux-next build (x86_64
allmodconfig) failed like this:
kernel/debug/kdb/kdb_support.c: In function 'kdb_strdup':
kernel/debug/kdb/kdb_support.c:309: error: implicit declaration of function 'kmalloc'
kernel/debug/kdb/kdb_support.c:309: warning: initialization makes pointer from integer without a cast
kernel/debug/kdb/kdb_support.c: In function 'debug_kfree':
kernel/debug/kdb/kdb_support.c:810: 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 5572dd736e5577dfefafe2ad3b54760e8323e33d ("kdb: core for kgdb
back end (1 of 2)") from the kgdb tree.
I applied the following merge fixup patch which should be applied to the
kdbg tree (see Documentation/SubmitChecklist Rule #1 :-)).
