Update of /projects/cvsroot/pvfs2/src/server/request-scheduler
In directory parlweb1:/tmp/cvs-serv19046/src/server/request-scheduler
Modified Files:
Tag: small-file-branch
request-scheduler.c request-scheduler.h
Log Message:
Big pile-o' changes to make Pete go mad.
The main changes are the implementation of the stuffed create path (now just the create state machine and operation), and the beginnings of the "unstuff" operation.
This also includes the request scheduler and state machine cleanups (required for using prelude with batch_remove) and whatever else I may have happened to change along the way.
This code is able to create files, but writing to them is almost guaranteed to break.
