Subject: Am I thinking correctly?

Message-ID: <PFEILFFLMPNHAOBNBGPJGEHDCHAA.ext3crypt@comcast.net> (raw)
I'm working on a masters project for PSU. It requires that I modify the
ext3 and fs code in the kernel proper.
The idea is to encrypt data just prior to it being written to disk. I've
created a new version of __block_write_full_page (which is called from
writepage) to allocate a new (GFP_NOFS) page, setup the buffer_head list and
copy the data to the new page (and encrypt it too). When I do this, the
data is not written to disk from the new buffer_head that I submit using
submit_bh(). I've treked through this code and I'm convinced I'm down the
right path. Am I? Any assistance would be appreciated.
