Subject: [PATCH] fix stack dbuf_hold_impl
|
|
|
|
This commit preserves the recursive function dbuf_hold_impl() but moves
|
|
the local variables and function arguments to the heap to minimize
|
|
the stack frame size. Enough space is initially allocated on the
|
|
stack for 20 levels of recursion. This technique was based on commit
|
|
34229a2f2ac07363f64ddd63e014964fff2f0671 which reduced stack usage of
|
|
traverse_visitbp().
