Revision 655042cc1406fcec20aa7ffd7d790ada18ac5211 authored by Vivek Goyal on 14 October 2016, 01:03:36 UTC, committed by Al Viro on 15 October 2016, 00:00:34 UTC
ovl_fill_super calls ovl_new_inode to create a root inode for the new superblock before initializing sb->s_xattr. This wrongly causes IOP_XATTR to be cleared in i_opflags of the new inode, causing SELinux to log the following message: SELinux: (dev overlay, type overlay) has no xattr support Fix this by initializing sb->s_xattr and similar fields before calling ovl_new_inode.
