[svn-r14020] Description:
Correct error in size of v2 B-tree metadata prefix, which could cause too many entries to get inserted into a node, eventually causing either a file corruption bug (if debugging asserts were off) or a core dump on the assertion which checked this. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
