Hi Jens,
Today's linux-next build (powerpc ppc64_defconfig) failed like this:
fs/sync.c: In function 'sys_sync':
fs/sync.c:121: error: implicit declaration of function 'wakeup_pdflush'
Caused by commit 1728603e84b339be5d5abd392ed3ec5936253863 ("writeback:
switch to per-bdi threads for flushing data") from the block tree
interacting with commit 3beab0b42413e83a7907db7176b54c840fc75a81
("sys_sync(): fix 16% performance regression in ffsb create_4k test")
from Linus' tree.
I added the following patch as part of the block tree merge for today. I
have no idea if it is correct.
