Whenever ReactOS finishes its operations onto the registry and unlocks it, a lazy flush is invoked to do an eventual flushing of the registry to the backing storage of the system. Except that... lazy flushing never comes into place.
This is because whenever CmpLazyFlush is called that sets up a timer which needs to expire in order to trigger the lazy flusher engine worker. However, registry locking/unlocking is a frequent occurrence, mainly when on desktop. Therefore as a matter of fact, CmpLazyFlush keeps removing and inserting the timer and the lazy flusher will never kick in that way.
Ironically the lazy flusher actually does the flushing when on USETUP installation phase because during text-mode setup installation in ReactOS the frequency of registry operations is actually less so the timer has the opportunity to expire and fire up the flusher.
In addition to that, we must queue a lazy flush when marking cells as dirty because such dirty data has to be flushed down to the media storage of the system. Of course, the real place where lazy flushing operation is done should be in a subset helper like HvMarkDirty that marks parts of a hive as dirty but since we do not have that, we'll be lazy flushing the registry during cells dirty marking instead for now.
CORE-18303
Loosely based on the deprecated ReactOS-specific SmExecuteProgram().
On server-side, we lookup into the list of deferred subsystems that
has been initialized at init time.
Dedicated to Justin Miller (The_DarkFire) work on reviving the
POSIX subsystem!
This DLL was exporting legacy NT-incompatible or ROS-specific SM client
functions, that have been since 10 years now (2012) replaced by the new
NT-compatible SM:
- SmConnectApiPort(): was just SmConnectToSm().
- SmCompleteSession():
The legacy SMSS used it for when a subsystem initialization was finished.
Now (NT-compatible) this function is called by subsystems **only** when a
subsystem session **terminates**: SmSessionComplete().
- SmExecuteProgram(): was just the client side of SmLoadDeferedSubSystem()
(whose server side is not implemented yet). The legacy SM "old" SmExecPgm
implementation actually was "SmLoadDeferedSubSystem"...
- SmLookupSubsystem(): is a utility-only function to read any registry value
inside "Session Manager\SubSystems".
Move SMDLL's readme into SMLIB and update its contents.
Collect some residual useful functions into smutils.c (and moved in SMLIB,
though not compiled yet):
- SmExecuteProgram(), now implemented as a wrapper around SmExecPgm();
- SmLookupSubsystem(), described above;
- SmQueryInformation(), that retrieves a list of currently-running subsystems.
[SMLIB] Validate SbApiPortName's length in SmConnectToSm().
Fix CommandLine length validation in SmStartCsr().
Add documentation (+ SAL annotations) to the NT-compatible SMSS client functions.
smmsg.h: Add both Win32 and Win64 struct sizes C_ASSERTs for those whose size
change between these two processor architecture sizes.
[SMLIB] Introduce SmSendMsgToSm() as helper to send data into the SM LPC port.
+ Make the other API functions use it.
It should be observed that in Vista+, both functions SmConnectToSm() and this
new SmSendMsgToSm() are exported by NTDLL under the names RtlConnectToSm()
and RtlSendMsgToSm() (and use the same signature).
See: https://www.geoffchappell.com/studies/windows/win32/ntdll/history/names60.htm
[NTDLL] Correctly stub RtlConnectToSm() and RtlSendMsgToSm().
[NTDLL_VISTA] Link to SMLIB and simply export RtlConnectToSm() and RtlSendMsgToSm().
Clicking "Edit compatibility modes" button in the "Compatibility" tab
opens a window centered on the parent window. If we move the parent
window to one of the screen edges and then click this button again,
the new window will appear off screen.
Adjust position of created window, so now it would be completely visible.

This header is included by ntoskrnl which effectively disabled all PAGED_CODE checks since 2015. Thanks Alex.
Instead define _BLDR_ when building cmlib, which will avoid trying to import KeGetCurrentIrql()
- Add some missing ARM64 exports to ntdll, kernel32 and user32
- Create mmtypes header file based on WoA debug symbols
- Get the remaining headers in order, so we can build ARM64 apps
- Adjust subsystem version for binaries so they can run on WoA host
- Get calc, notepad and more base apps to build for ARM64 platform
