git tree for reiser4 development

git tree for reiser4 development

[Arkadiusz Miskiewicz]

Hi.

How reiser4 is developed - is there a public git repo with development tree 
and if so, where?

Thanks,

There is a Namesys corporative git repo, but currently it is
unavailable for public. The last commit was at November 2006,
or so. I might want to put it to kernel.org..

Thanks,
Edward.

Ouh, mm currently has no reiser4 , so I guess it was dropped.

Was looking for something newer - close to 2.6.36 (was actually looking for a 
2.6.36 alpha/beta/rc/final patch).

No, it wasn't.
Just disabled by "depends on BROKEN" in Kconfig:
it needs to be adjusted to the latest VFS changes.

reiser4-for-2.6.36 stuff is not yet ready.

Dirty, untested change for .35 patch ... I assume "real" update needs more than this?

Yes, much more:
reiser4-for-2.6.35 stuff works incorrectly.
->write_end() methods of both file plugins should be fixed.
Also reiser4 needs a ->sync_fs() method of super operations.
I am working on this at my spare time.
