[also build test ERROR on next-20191031]
[cannot apply to v5.4-rc5]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

Re: [RFC PATCH v2] f2fs: support data compression
by kbuild test robot
Hi Chao,
[FYI, it's a private test report for your RFC patch.]
[auto build test ERROR on f2fs/dev-test]
[cannot apply to v5.4-rc5 next-20191031]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
