...ops in their definition of superblocks). This is necessary to get the largest piece of IR in which the memory operations can be enumerated in order to record the addresses of the memory accesses into a fixed-size buffer. So far I was using my home-brewed structure to hold the superblocks: struct SBlock { BlockSet blocks; llvm::BasicBlock *entry; BlockSet exits; InstSet mops_to_instrument; int num_mops; SBlock() : num_mops(0) {} }; and several functions that split basic blocks to eliminate calls from them, traverse the call graph and create the SBlock instances from the basic blocks....

Changes v1-v2: - Remove restriction that BTRFS_IOC_GET_DEVICE_STATS is a privileged operation - Cast u64 to unsigned long long for printf() Changes v2-v3: - Rebased on Chris'' current master Changes v3-v4: - Add padding at end of ioctl structure Changes v4-v5: - The statistic members in the ioctl are now organized as an array of 64 bit values. Symbolic names for the array indexes

Hi all, I was intending on trying out gjournal on a new disk i've added in my desktop. I had a look to see what the most recent patch provided by Pawel and found http://people.freebsd.org/~pjd/patches/gjournal6_20061024.patch I created the directories as per Pawel's original post (http://lists.freebsd.org/pipermail/freebsd-fs/2006-June/001962.html) and the patch succeeded with no failed

Two machines (NFS Server: running ZFS / Client: disk-less), both are running FreeBSD r253506. The NFS client starts to deadlock processes within a few hours. It usually gets worse from there on. The processes stay in "D" state. I haven't been able to reproduce it when I want it to happen. I only have to wait a few hours until the deadlocks occur when traffic to the client machine
