The current fsfreeze API lacks a method to check the current freeze status of a superblock. One might be tempted to think that a new vfs ioctl is all we need, but with the current implemetation of fsfreeze it it is possible to umount a freezed filesystem, which means that the only way to check the freeze status is through the block device. For a moment I thought I could get without the vfs version but then I realized that the block device ioctl would not play well with btrfs. Because of all of the above I ended up implementing both. Al also suggested [1] a thaw-by-block-device ioctl which I am currently working on.
