From aca77cad36c74c9a06f1b1d380e3b105795dc569 Mon Sep 17 00:00:00 2001 From: Tahsin Erdogan Date: Tue, 4 Jul 2017 23:53:59 -0400 Subject: [PATCH] fuse2fs: refuse to mount fs with ea_inode feature ext2fs_xattr_set() currently does not support creating xattr inodes, so allowing fuse2fs to mount a filesystem with ea_inode feature could lead to corruption. Refuse to mount if the ea_inode feature is set.
