477792856e [NTOS:Mm] Replace YieldProcessor() with KeDelayExecutionThread() 
These are used in the paging path, when the page is currently in the process of being read from or written to the disk. While YieldProcessor() provides the chance to switch context to the other paging thread, it only does so, once the current thread's quantum has expired. On a single CPU system this effectively leads to busy waiting for the rest of the quantum. On SMP systems this could succeed earlier, thus reducing latency, but it would still contribute to high CPU usage, while waiting for the IO operation to complete, which is not what we want.
Using KeDelayExecutionThread() will instantly allow another thread to run, providing enough time to complete the IO operation.

[NTOS:MM] MmCanFileBeTruncated: Check whether second (optional) parameter was passed (#5248) 
Second parameter is optional, so mark it as such and check whether it was passed. Fixes a sporadic 0x24 bugcheck caused by access violation when running ReactOS on NTFS volume with WinXP ntfs.sys.

[NTOSKRNL] Flush file to disk when deleting file mappings (#4302) 
CORE-17627
When closing a file, fastfat zeroes it out from ValidDataLength up to the end of the file.
The ValidDataLength field is updated when the file content is actually written to disk.
There is currently a race between the file-close path and the page out path, leading to potential file corruptions when the zeroing happens after the memory has been flushed to disk.

Fix this by actually flushing the file to disk when unmapping files, with file lock acquired. This way, the FS driver cannot zero out the tail of the file while we're actually flushing it to disk.
