 Module Name:   src
 Committed By:  hannken
 Date:          Wed Apr 27 07:24:53 UTC 2011
 Modified Files:
        src/sys/ufs/ffs: ffs_extern.h ffs_vfsops.c ffs_vnops.c
 Log Message:
 Cleanup ffs fsync and make devices on wapbl enabled file systems work here:
 - Replace the ugly sync loop in ffs_full_fsync() and ffs_vfs_fsync() with
   vflushbuf().  This loop is a relic of softdeps and not needed anymore.
 - Add ffs_spec_fsync() for device nodes on ffs file systems that calls
   spec_fsync() like all other file systems do and then updates the ctime.
 Discussed on tech-kern.
 Should fix PRs:
 PR #41192 wapbl diagnostic panic during cgdconfig
 PR #41977 kernel diagnostic assertion "rw_lock_held(&wl->wl_rwlock)" failed
 PR #42149 wapbl locking panic if watching DVD
 PR #42551 Lockdebug assert in wapbl when running zpool
