Hi Waiman,
[auto build test ERROR on ext4/dev]
[also build test ERROR on v4.6-rc2 next-20160408]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]
url: https://github.com/0day-ci/linux/commits/Waiman-Long/ext4-Improve-parallel-I-O-performance-on-NVDIMM/20160409-002128
base: https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git dev
config: um-x86_64_defconfig (attached as .config)
reproduce:
# save the attached .config to linux build tree
make ARCH=um SUBARCH=x86_64
Note: the linux-review/Waiman-Long/ext4-Improve-parallel-I-O-performance-on-NVDIMM/20160409-002128 HEAD 712a939b92b9178cb79df4050bba8e6b1d03ca63 builds fine.
It only hurts bisectibility.
