dopageflush

Description

Controls whether memory is examined for modified pages during fsflush invocations. In each invocation of fsflush, the number of physical memory pages in the system is determined. This number might have changed because of a dynamic reconfiguration operation. Each invocation scans by using this algorithm: total number of pages x tune_t_fsflushr / autoup pages
