Module Name:    src
Committed By:   hannken
Date:           Wed Feb 20 10:08:38 UTC 2019

Modified Files:
        src/external/cddl/osnet/dist/uts/common/fs/zfs: zfs_ctldir.c
        src/sys/kern: vfs_mount.c vfs_trans.c

Log Message:
Move fstrans_unmount() to vfs_rele(), just before it would free the mount.
Don't take a mount reference for fstrans as it gets notified about the release.

Defer the final free of the mount to fstrans_mount_dtor() when fstrans
has released all references to this mount.  Prevents the mount's memory
to be reused as a new mount before fstrans released all references.

Address PR kern/53928 modules/t_builtin:disable test case randomly fails.
