Wrapper fs Code (wrapfs)

[UZAIR LAKHANI <uzairr_bs1b@yahoo.com>]

Hello All, 

I have some questions regarding the wrapper fs code
downloaded from filesystems.org

The questions are below:

(1) Finding out the meanings of FIST_FILTER_SCA and   
              FIST_FILTER_DATA

(2) How wrapfs handles the dentry and inode cache of
wrapfs and not the actual fs. While reading the code
of struct dentry_operations of wrapfs, I found out
that the operations involved don't do anything to the
wrapfs dentry cache, these operations only deal with
the actual fs dcache using actual fs dentry
operations. 

(3) When I update some file in the actual fs e.g. a
file in the folder on ext3 file system, the changes
done there are not reflected on the same file on
wrapper fs but the vice versa is working correctly.

I want some details regarding these questions. Hope I
am able to convey my point.

Thanks,
Uzair Lakhani,
Karachi, Pakistan.
