I've done when I was experimenting with rwsems at zero-th iteration of
batch discard support.
v2: - disable grab in current context unconditionally, not only if !BA_FORCE
Ivan Shapovalov (3):
reiser4: block_alloc: improve error handling in reiser4_grab_reserved().
reiser4: block_alloc: sanitize grab_enabled modifications.
reiser4: do not mess with grab_enabled; instead, use BA_FORCE.

ping, what's the status?
This is in "upstream" already.

I'll send another round of discard patches shortly... That is, once I figure
out how to explain in comments the sheer amount of happily coinciding subtle
details, whose coincidence makes everything actually work. :/
Note, that basic discard stuff is also in "upstream".
So, please, make sure that your patches are "re-based"
BTW, could you please check that I've rebased your "precise discard" patch
correctly?

I suggest to start with implementing the bitmap primitives that
I talked about. Just to avoid extra-work..
Thanks,
Edward.
