Depends on which kernel release you're on. A process shouldn't need that kind of processing just to determine if a disk can be accessed. It seems to be fundamentally wrong to ask for more RAM than it takes to read the FST on access. Mmaping a file when reading it makes sense, mmaping the entire disk does not. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
