Re: [PATCH v2] ovl: provide real_file() and overlayfs get_unmapped_area()
Hi Mike,
I love your patch! Yet something to improve:
[auto build test ERROR on miklos-vfs/overlayfs-next]
[also build test ERROR on linus/master v5.7-rc7]
[cannot apply to linux/master next-20200526]
[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]
