4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Theodore Ts'o <tytso@xxxxxxx> commit a2fd66d069d86d793e9d39d4079b96f46d13f237 upstream. Newer versions of mount parse the lazytime feature and pass it to the mount system call via the flags field in the mount system call, removing the lazytime string from the mount options list. So we need to check for the presence of MS_LAZYTIME and set it in sb->s_flags in order for this flag to be set on a remount.
