Revision	Date	Author	Comments
1.11	08-Jul-2022	hannken	Handle IMNT_GONE on the file system we want suspended not its lowest mount we really suspend.
1.10	22-Dec-2019	ad	Make mntvnode_lock per-mount, and address false sharing of struct mount.
1.9	20-Feb-2019	hannken	Attach "mnt_transinfo" to "dead_rootmount" so every mount has a valid "mnt_transinfo" and remove now unneeded flag IMNT_HAS_TRANS. Run fstrans_start()/fstrans_done() on dead_rootmount if FSTRANS_DEAD_ENABLED. Should become the default for DIAGNOSTIC in the future.
1.8	05-Oct-2018	hannken	Bring back three state file system suspension: NORMAL -> SUSPENDING -> SUSPENDED and add operation fstrans_start_lazy() that only blocks while SUSPENDED. Change vndthread() support operation handle_with_rdwr() to bracket its file system operations by fstrans_start_lazy() and fstrans_done(). PR kern/53624 (dom0 freeze on domU exit)
1.7	24-May-2017	hannken	branches: 1.7.2; 1.7.8; 1.7.10; With dounmount() working on a suspended file system remove no longer needed fields mnt_busynest and mnt_unmounting from struct mount. Welcome to 7.99.73
1.6	07-May-2017	hannken	Return ENOENT if trying to suspend an unmounted file system.
1.5	30-Mar-2017	hannken	branches: 1.5.4; Change last users of FSTRANS_LAZY to FSTRANS_SHARED and change genfs_suspendctl() to move from FSTRANS_NORMAL to FSTRANS_SUSPENDED and vice versa.
1.4	17-Feb-2017	hannken	Add generic genfs_suspendctl() and use it for all file systems. Layered file systems need work.
1.3	30-Nov-2009	pooka	branches: 1.3.22; 1.3.40; 1.3.44; 1.3.48; Introduce genfs_statvfs() as pretty much a no-info statvfs and convert several pseudo file systems to use it.
