commit 62dc4597 upstream. In real scenario, there could be several threads accessing xattrs of the same xattr-uninitialized inode, and init_inode_xattrs() almost at the same time. That's actually an unexpected behavior, this patch closes the race. Fixes: b17500a0 ("staging: erofs: introduce xattr & acl support") Cc: <stable@vger.kernel.org> # 4.19+ Reviewed-by:
