This is a regression test case to verify whether the CP_TRIMMED_FLAG is
properly set after performing the following steps:
1. mount the f2fs filesystem
2. create a file, write data to it, then delete the file
3. unmount the filesystem
4. verify that the 'trimmed' flag is set in the checkpoint state
This patch add a ioctl to estimate compression gain. In user mode compression,
users can define
the interval between clusters for estimation sampling before compress and
release ioctl to a file.
This can help users to decide whether to do compress in a fast way, especially
for some large files.
