The following items are still unaddressed:

2. Running iput() in entd() is a bit surprising. iirc there are various
ways
in which this can recur into the filesystem, perform I/O, etc. I
guess it
works..
But again, it will hammer inode_lock.

3. the writeout logic in entd_flush() is interesting (as in "holy cow").
It's very central and really needs some good comments describing
what's
going on in there - what problems are being solved, which decisions
were
taken and why, etc.

4. reiser4_wait_page_writeback() needs commenting.

5. reading the comment in txnmgr.c regarding MAP_SHARED pages: a number
of
things have changed since then. We have page-becoming-writeable
notifications and probably soon we'll always take a pagefault when a
MAP_SHARED page transitions from pte-clean to pte-dirty (although I
wouldn't
recommend that a filesystem rely upon the latter for a while yet).

Feel free to address them.

Thanks,
Edward.
Has the number of items reduced at all ?
just curious

I haven't looked at the code since several years. But as far as I have followed the development, all of the patch sets since then (April 2009) were only of cosmetical nature, or said with other words, to keep it coping with changes at different positions, like eg. VFS.
And in a handful of blogs I got no additional/other informations, despite that the maintainer is working at a company in the field of another file system since the end of last year, so that he has only few time for Reiser FSs, and also that the opinions are that the project is dead.


We also found out that, like the ReiserFS maintainer, the starter of this thread, who is also the starter and maintainer of the ReiserFS wiki as well as the filler of the ReiserFS wiki with copyrighted materials, has changed to the development of the Btrfs file system, too. For example in June he made a patch with:

- tristate "Btrfs filesystem (EXPERIMENTAL) Unstable disk format"
- depends on EXPERIMENTAL
+ tristate "Btrfs filesystem"

so that "Btrfs is highly experimental" could be substituted with "Btrfs is under heavy development".

Again, this gives something to think about the engagement of the person, as well. We always had the impression that he, like a handful of other persons, was only here at reiserfs to mess up the R4 development, to work and make politics against this project, and to disturb the developers and their businesses.
Btw.: In the case of copying copyrighted materials into the ReiserFS wiki the kernel.org administrator was already informed by us, but explained that it's up to [Hans Reiser] to ask for removing these materials from kernel.org, which is an argumentation we are unable to understand, because the kernel.org administrator does know that copyrighted materials are illegally publicated on the kernel.org website.
