ext4: set lazytime on remount if MS_LAZYTIME is set by mount
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. Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org
