FWIW, with your .config I'm seeing the same leak (shut down by turning spinlock debugging off, it's split page table locks that end up leaking when they are separately allocated) *and* xfs/253 seems to be sitting there indefinitely once we get to it - about 100% system time, no blocked processes, xfs_db running all the time for hours. No oopsen on halt with that sucker skipped *or* interrupted halfway through. Setup is kvm on 3.3GHz amd64 6-core, with 4Gb given to guest (after having one too many OOMs on leaks). virtio disk, with raw image sitting in a file on host, xfstests from current git, squeeze/amd64 userland on guest. Reasonably fast host disks (not that the sucker had been IO-bound, anyway). Tried both with UP and 4-way SMP guest, same picture on both... _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
