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.
