Since 042stab056.5:

  • [cfq] kernel BUG at block/cfq-iosched.c:386 has been fixed (PCLIN-30890)
  • [fuse] added possibility to disable fuse O_DIRECT with help of fs.fuse_ext_caps sysctl (enabled by default) (debug for PSBM-13075)
  • [fuse] flush writeback data on file close. In particular this fixes checkpointing (PSBM-13226)
  • [fuse] several other bugfixes
  • [quota] remounting of FS with quota on ploop could crash host (PSBM-13231)
  • [fs/writeback] writeback writer throttler algorithm has been enhanced
  • [mount namespaces] mount namespaces support for has been added. This is required for Fedora 17 (PSBM-13004). Note: online migration support has not been added yet
  • [cpt] kernel BUG at kernel/cpt/rst_socket.c:407 (on a self-connected socket restore) fixed (PSBM-13367)
  • [cpt] sleep-in-atomic at dumping cgroup has been fixes (PSBM-13297)
  • [cpt] timerfs irq-safe locking has been fixed
  • [cpt] false positive error messages "_rst_get_object: wrong object type" has been fixed (PSBM-13303)
  • [fuse] "fs.fuse_ext_caps" sysctl has been removed. Now we need to provide fuse mount options to enable features:
    • "writeback_enable" mount option to enable writeback for fuse mount
    • "direct_enable" mount option to enable direct IO for fuse mount
  • [fuse] show writeback and dio options in proc
  • [fuse] file release should make sure writeback is finished
  • [iov_iter] direct_IO_page interface has been added. Required for efficient fuse io_kaio (PSBM-12830)
  • [oom] oom reports now the current fuse writeback pages counter
  • [time] CT uptime is calculated incorrectly in cases like host suspend (PCLIN-30011)
  • [fairsched] accuracy of idle/iowait time stats reported through /proc/stat has been increased (PCLIN-30724)
  • [fairsched] context switch latency on an almost idle node has been significantly decreased (PSBM-11477)
  • [ploop] support for 'expanded' format to io_kaio, support for snapshot, merge and pcopy (migrate) operations has been added (PSBM-12830)
  • [ploop] we support only ploop over NFS v3 => ploop mount over NFSv4 has been prohibited (PSBM-13376)
  • [ploop] ploop balloon discard could ignore errors and hang (PSBM-13290)
  • [ovs/ipv6] kernel ABI has been restored, hypervisor modules should compile fine now (PSBM-13383)
  • [ploop] disable ENOSPC checks for preallocated and raw images
  • [blkcg] allocate per-cpu statistics from worker thread
  • [ipv6] change neighbour table hash for ipv6
