[PATCH v9 0/2] MR7115: Added support of case FileAllocationInformation in SetFileInformationByHandle
This MR intends to add support for the case FileAllocationInformation in function SetFileInformationByHandle of library kernelbase.dll. The code is based on my understanding of [MS documentation](https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/ns-ntif...)
No test was added, because other cases that could have helped doing so (FileEndOfFileInformation) do not have neither.
-- v9: Added tests for class FILE_INFORMATION_ALLOCATION in setFileInformationByHandle Added support for class FILE_INFORMATION_ALLOCATION in setFileInformationByHandle

@hans I cleaned the commit history as you requested and added a prepocessor directive in both code and tests, since MacOS seemingly doesn't provide fallocate. Now, CI seems fully happy.
Hans Leidekker (@hans) commented about dlls/ntdll/tests/file.c:
Please test what happens to the file size (using GetFileSize()) with an allocation size larger than the current file size as well as an allocation size smaller than the current size.
Hans Leidekker (@hans) commented about dlls/ntdll/tests/file.c:
You can't use this ifdef in tests.
Hans Leidekker (@hans) commented about dlls/ntdll/unix/file.c:
This should use a new configure check for fallocate() instead.
