    ubifs: Massage assert in ubifs_xattr_set() wrt. init_xattrs · d8db5b1c
    Xiaolei Li authored
    The inode is not locked in init_xattrs when creating a new inode.
    
    Without this patch, there will occurs assert when booting or creating
    a new file, if the kernel config CONFIG_SECURITY_SMACK is enabled.
