v3 patch posted to correct 2nd problem (ret_buf returning to
blk_freelist instead of buf_freelist).
The pool bufcount is decremented as part of ret_buf processing. It
reflects the number of allocated buffers and will return to 0 naturally
when the last allocated buffer is freed, so this should not be set to 0
unconditionally.
It should, because what currently happens during pool creation:
- bufcount is set to 0
- new buffers are pushed to a free list via ret_buf()
- ret_buf() decrements bufcount -> bufcount underflows
So after buffer is created its bufcount is not zero. As a result buffer
can't be destroyed.
