Abstract:

    The pool tag definitions for SMB mini redirector

Notes:

   This file contains all the pool tag definitions related to the SMB mini redirector.
   The mechanism is intended to balance the number of pool tags to be used with the
   total number of tags available in the system.

   By specifying special flags the total number of tags consumed by the mini redirector
   can be controlled. For most builds the tags should be aliased such that about
   6 tags are consumed by the mini redirector. In special builds the aliasing of tags
   will be suppressed, thereby consuming more tags to track down memory leaks easily.

   The following are the major tags ....

      1) SmCe -- the Smb Mini Redirector connection engine.

      2) SmOe -- the Smb Mini redirector ordinary exchange related allocation.

      3) SmAd -- the Smb Mini redirector ADMIN exchange/session setup/tree connect etc.

      4) SmRw -- the Smb mini redirector read/write paths

      5) SmTr -- the Transact exchange related allocations

      6) SmMs -- the miscellanous category.
