These are mostly equivalent transformations (aside from the first patch)
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.
Hm.. I didn't see it..
Well, then a follow-up fix should be applied, as described in one of previous
messages, or this should be reverted.
With that patch things looked better and you promised
"equivalent transform". OK, I'll roll it back then.
Thanks,
Edward.

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"
Yes, I'll ensure that everything can be applied cleanly.
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..
If I understand you correctly, then I've already done that.
But let's first deal with this (current) patchset; it's broken. Sorry for
creating more problems than solving.
Thanks,
