The branch, master has been updated
via adf4833... This patch looks bigger than it is. It does 2 things. 1). Renames smbpid -> smblctx in our locking code. 2). Widens smblctx to 64-bits internally. Preparing to use the SMB2 handle as the locking context.
from 6fd4861... s4-devel: a very useful script when dealing with library/linking issues
