PR kern/40562 busy loop in ffs_sync when unmounting a file system
PR kern/40525 panic: ffs_valloc: dup alloc

- A fix for an issue that can lead to "ffs_valloc: dup" due to dirty cg
  buffers being invalidated. Problem discovered and patch by dholland@.

- If the syncer fails to lazily sync a vnode due to lock contention,
  retry 1 second later instead of 30 seconds later.

- Flush inode atime updates every ~10 seconds (this makes most sense with
  logging). Presently they didn't hit the disk for read-only files or
  devices until the file system was unmounted. It would be better to trickle
  the updates out but that would require more extensive changes.

- Fix issues with file system corruption, busy looping and other nasty
  problems when logging and non-logging file systems are intermixed,
  with one being the root file system.

- For logging, do not flush metadata on an inode-at-a-time basis if the sync
  has been requested by ioflush. Previously, we could try hundreds of log
  sync operations a second due to inode update activity, causing the syncer
  to fall behind and metadata updates to be serialized across the entire
  file system. Instead, burst out metadata and log flushes at a minimum
  interval of every 10 seconds on an active file system (happens more often
  if the log becomes full). Note this does not change the operation of
  fsync() etc.

- With the flush issue fixed, re-enable concurrent metadata updates in
  vfs_wapbl.c.
