Description Raghavendra G 2009-08-08 17:33:06 UTC 
Due to the way check is done for O_RDONLY in wb_open_cbk and wb_create_cbk, window-size is getting set to 0 for all the files. The correct fix should use O_ACCMODE while checking for O_RDONLY flags.

Fix should also be done in read-ahead and filter.
