tooling patches

[Sachin Patel]

Would one of the committers mind checking in the patches for 884,885, 
and 888?  I'm making changes on source files that already have existing 
pending patches in these jiras and don't want to introduce new patches 
until their checked to avoid conflicts when merging.  For my knowledge, 
how is this handled? Are cumulative patches easily handled?  i.e What 
happens if i have Patch-A based on revision 1 on File-A.  Then I 
introduce Patch-B on File-A also based on revision 1 (but includes 
changes that went into Patch A).  Since both of the patches are based on 
the same revision # I would assume that only one of the patches can be 
applied without errors or conflicts.  What happens when the second patch 
is applied since the patch is no longer based on the revision specified 
in the patch file? If the second patch cannot be applied, how is one 
expected to know which patch to throw out?

Thanks.
Sachin.
