The following items are still unaddressed:
1. running igrab() in the writepage() path is really going to hammer
inode_lock. Something else will need to be done here.
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.
Cheerio
